Another Agent, Allison Marsh, walks up and says that Reggie Cole has been working undercover for the FBI to take down a crime boss by the name of Jimmy Cannon. Danny knows the guy and says that he is a dangerous man. Marsh says that Cannon was coming in to visit his son. She says that they are going to take over the investigation, but Steve says that he is going to investigate it as well because there is a leak in her office.

Kevin comes in to see Reggie and asks if he is going to get the men who hurt Lisa. Reggie says that he is. Kono shows the video that she got from the crime scene and it is grainy. However, they see that Reggie did hit one of the gunmen and Steve tells the team to investigate around where the truck was. Steve says that he is going to go and get some “evidence”. They pull up to Jimmy Cannon’s house and the guard gives Steve money to leave. However, Steve drives through the front gate.

Meanwhile, Kono talks to Kevin and he says that his father told him not to help the police, but Kono says that she is special police just like Reggie. She asks if Kevin recognizes anyone from pictures. Kono pulls out a photo from the video and he recognizes the man, but they have no ID. Steve asks where Danny would go and Danny says that he wouldn’t break any laws though. Kono calls and says that the shooter is a new hire possibly. Chin Ho says that there were three agents to watch Reggie, but Allison Marsh was absent and Steve says that they found their leak.
He interrogates Marsh and asks how much Cannon was paying her. She says that she did lie to Steve about her daughter and says that she framed her ex-husband so that he wouldn’t take her daughter out of the country and told Newman that she would be right back. Newman said that he could handle things. She says that she is not the leak. Kono comes in and says that the Squad car that Reggie took is found. Danny sees that the GPS tracker is destroyed. They see the computer database and sees that 1996 White Explorer. Danny pulls up Boakye and they rush to the address to find that Boakye is dead.

Reggie says that he has a way to find him and shows Steve that the bullets used in Boakye’s gun. The bullets have half the force. Steve realizes that Agent Newman is the leak because the bullet wasn’t meant to kill him. They go to the hospital and tell that they know that he got $500,000 for giving information. He says that Nelson Ling is the guy that paid him. They go to his residence and they catch him. He draws on Reggie and is shot.
