Jerry Smith (ジェリー・スミス Jerī Sumisu) is a Metropolitan Police Service officer and partner of the rookie officer Emily Thompson. With Eda's help, the two officers were assigned to foil the Advanced IRA's terrorist plot in the United Kingdom.

Jerry is a tall British man with a large build, pale skin, and short, wavy blond hair. He often wears a light-colored overcoat with a dark-colored suit and pants, a light-colored dress shirt, a necktie, and black shoes. He carries a pistol for a weapon.

Jerry is a firm adherent to following police procedures in contrast to those who use rough or unorthodox methods when interacting with criminal suspects. He is skilled in marksmanship and prefers that those whom he works with share his same lawful mindset.

When the British government discovered that the Advanced Irish Republican Army, an offshoot of the Provisional IRA, acquired Stinger missiles, they prioritized an investigation to stop a potential terrorist attack by the group and seize the weapons. Accordingly, Jerry and his new partner Emily Thompson were assigned by their police director at New Scotland Yard to use their informants connected to the Advanced IRA to aid in their operation. Additionally, the Met agreed to let the U.S. Central Intelligence Agency join them as a pursuit team, so Eda came to London to help out the two officers. At an airport in London, Jerry and Emily waited for the CIA agent's arrival at the terminal. The two officers introduced themselves and reiterated their goal to retrieve the Stinger missiles. Eda was amused as to why a young woman like Emily was working for Scotland Yard, prompting Jerry to vouch that she was an excellent detective who graduated at the top of her class.

Getting into their car, Jerry likewise claimed he was surprised at Eda's youth given their important case. Nonetheless, he clarified that his surprise was a compliment. When Eda asked if they had any leads, Emily answered that they had an informant with a good lead but asserted that they had to return to police headquarters and speak with the director first. Thinking the visit would be unnecessary, Eda recommended that they meet with the informant first. Jerry remained silent as Emily retorted that she could not do whatever she wanted, but the CIA agent rhetorically asked her if she understood the Stinger missiles could be used in a terrorist attack in just one or two days. Subsequently, the three of them went to the informant, who was immediately pushed to the ground by Eda. Grabbing the scared man, Eda demanded to know what he knew about the Advanced IRA's secret weapons ring's shipment from the United States. Jerry ordered her to stop, but she asserted that they were in a hurry, slapping the informant and threatening to injure him further if he refused to talk.

Afterward, although the two officers wanted Eda to remain with them, the CIA agent discreetly swiped Jerry's car keys and headed to the site in Gravesend the informant told her about. Jerry and Emily quickly returned to police headquarters, where their director chastised the former for not paying attention. Yelling again, the director ordered them to get moving because they already knew where Eda was headed, adding that they needed to seize both the CIA agent and the illicit weapons. On the way to stop her, Jerry drove and compared Eda to a pompous Joan of Arc, though Emily disagreed and compared her to the American outlaw Belle Starr. He sped toward the container yard and emphasized that they could not let Eda have her way or else the Metropolitan Police would lose face in London. Emily wondered if they would make it in time, making Jerry tell her not to be so pessimistic. To their shock, they saw the smoke from the explosion resulting from an Advanced IRA fighter's grenade detonating near oil drums. Arriving outside the port area with other police officers, the speechless Jerry and Emily watched Eda emerge from the scene.

After the incident, the three of them returned to the informant as Eda interrogated him a second time, much to Jerry's chagrin. To his surprise, Eda pulled out her pistol and stuck it against the man's head, causing him to immediately confess he learned his information from Chester Shankly in Watford. Emily chastised Eda for her methods, to which the CIA agent asked what they wanted. While the policewoman declared that they would accompany her to the pub, Jerry, in agreement, yelled that they could not allow her to do whatever she wanted in London especially because of her waving her gun around so casually. He asked if she even had a permit for it and then had her sit in the backseat as he drove for them.

In Watford, as they entered the pub, Chester was shocked to see them and immediately ran out the back door, giving his identity away to the agents. At the door, the law enforcement officers were immediately pinned down by continuous gunfire from Cillian McGrath, the Advanced IRA's second-in-command. Realizing that it was an ambush, Eda asked the two officers to give her suppressive fire. Accordingly, Jerry and Emily covered for her as she shot at a couple of them. As Eda engaged in combat with Cillian, Jerry defeated the other fighters and covered for Emily as she ordered the Advanced IRA commander to freeze. However, Eda prevented her from aiming at him because she needed him alive, allowing him to escape. Angered, Emily shouted at Eda for allowing him to escape given his group's involvement in killing Met Police officers. Eda bluntly replied that she should not let personal vengeance blind her mission. Although Jerry advised Emily to calm down, he also criticized the "Yankee" for being out of line, glaring at her.

A short period later at a different pub, Jerry, Emily and Eda got some drinks. As Emily went to the counter, Eda requested Jerry to remove the girl from the mission due to her annoyance. Jerry rhetorically asked why she would insult the same person who saved her, adding that he had trust in Emily and thought CIA agents did not know any better. He reiterated that he did not take orders from Eda, who told him he could tell that to his boss. Jerry muttered that she really was a CIA agent after all given her attitude, confusing Eda since she claimed there was nothing else one could see in her. Returning to the table, Emily asked what they were talking about, with Jerry relaying to her that Eda disliked her. Not offended, Emily retorted that she was not trying to be liked, asserting that she could not let Eda mess up their investigation any further, especially because she was a member of the Stinger tracking team.

Impatient with both officers, Eda mentioned that she merely wanted to get her job over with so that she could go to the Padres game in her home country. After she left the pub, the baffled Emily wondered why she was acting weird while Jerry was confused about her drinking habits. He posited that Eda and the CIA might have another agenda other than tracking the Stinger. Not concerned, Emily commented that their primary focus was to stop the Advanced IRA terrorists. The next day, Jerry and the two women departed from New Scotland Yard, with Eda complaining that the former's meetings with police superiors seemed to be a waste of time. At that point, the CIA agent spotted a shady man exiting their car, startling him. Eda grabbed Jerry and Emily and yelled at them to get down, ducking as the car bomb detonated. As the smoke quickly cleared, Eda got up and pursued the fleeing perpetrator.

Shielding Emily, Jerry got up and asked if she was all right. She confirmed but admitted that her ear hurt, and they saw Eda up ahead. The two officers walked up to her to help her out after she disarmed the man, and she casually confirmed that the man, Morton, was indeed an Advanced IRA member. Alleging that Morton was merely a diversion, she relayed to the police officers that the Advanced IRA's next attack would supposedly happen at an air force base with the Stinger missiles involved. When Eda added that the attacker was just a blabbermouth, the officers joked that he was quite the cooperative bomber. Leaving the area, Eda asked them to forget their sarcasm and prepare to depart. Confused, the two officers agreed but were left bewildered at the ordeal. In a quick response, the British government had the air base halt all takeoffs and landings, also giving the police and military time to mobilize against a potential attack. Jerry drove for the three officers to raid the hideout, and he like Emily was angered that Eda kept the location details a secret since she had her own motivations for stopping the bombing. He asked to where they were going, so the CIA agent explained that the hideout was a few kilometers south of the air base. Soon driving into a neighborhood, Jerry asked Eda if they were close to the destination. Hearing her confirmation, Emily noted that the number of houses narrowed down their search field. Eda spotted the house and pointed out that it was most likely the place given that it faced the base, their window was open, and an unusual minivan was parked in the driveway. Though the CIA agent ordered Emily to run the minivan's license plate, Jerry professed that it would be unnecessary since he recognized the area code being Liverpool. Agreeing that was suspicious enough, Eda suggested that they pull around the street corner and split into two groups.

As they walked up to the house, Jerry and Emily agreed to take the front while Eda snuck around the back. At the front door, Jerry knocked but received no response, so Emily grasped onto the doorknob. Immediately, the Advanced IRA extremists shot a barrage of bullets through the door, forcing the officers to take cover. Inside, meanwhile, Eda and Cillian quickly clashed, causing the latter to urge Advanced IRA leader Michael Connolly to escape. Michael jumped out the window and onto the ground, but Jerry spotted him as he began fleeing. Jerry adamantly ordered Emily to pursue him despite her hesitancy so that the Advanced IRA leader did not escape. While Emily and Eda respectively engaged in gunfights with Michael and Cillian, Jerry successfully defeated the remaining IRA subordinates attempting to kill the officers. The exhausted Jerry was resting against a wall after having killed the extremists when Emily confirmed that she ended Michael's life, making the two agree that their fight was over. In the other room, they heard a single gunshot which was Cillian killing himself to prevent Eda from interrogating him. Rushing into the room, Jerry was disgusted to see the man's corpse, though his mission was complete.

Once the mission to foil the Advanced IRA had finished, Jerry and other Met Police leaders met up to discuss further action because the gun runners who gave weapons to the group were still at large. In the meeting, Jerry remained silent and listened to his partner relay to Eda that Chloe Reddington, the wife of the Advanced IRA's leader, received international calls from the United States indicating an arms deal due to her being the point of contact. Briefing Eda on her next step, she clarified that they would pose as Michael Connolly's messenger to Chloe and then contact the American smuggling ring by posing as Chloe. On the day of the disguised contact, during Eda's mission of posing as Chloe, Jerry and Emily waited in a van nearby. He teased his partner for her lack of faith in Eda's capability, which Emily angrily denied.

At that point, they saw Eda returning to the van, and to their surprise she informed them that she got a meeting set up in New York. Afterward, the three headed to an airport for Eda's departure from London. Jerry listened to Emily thank Eda for everything and professed she was glad they thwarted the airbase attack and effectively destroyed the Advanced IRA. Before bidding the police officers goodbye, Eda claimed she had a present for Emily and put it in Emily's chest pocket. Jerry was curious as to what it was, and Emily was puzzled upon discovering the "present" was Eda's expired ticket to the interleague game between the Padres and Angels.
