While apprehending him, Bishop stops Nolan from beating the suspect in a rage. A kidnapping victim is rescued, and Nolan and Bishop obtain a lead on the kidnapper. Nolan is assigned a rusty old car as punishment for damaging his vehicle. West is able to subdue a suspect without assistance. Nolan continues to face difficulties in navigating between his civilian instincts and how they affect his actions as a cop. Chen is stuck with a lazy new training officer while Bradford recovers, and winds up arresting a man for shoplifting. Nolan and Bishop arrest an addict for possession of drugs, but then learn that she stabbed a teenager dead in an argument. She then forces him to handle the arrest of a man on PCP, which he pulls off. West is questioned as to why he didn't fire his weapon, but Lopez covers for him.

Nolan prevents a woman from killing herself after she tries to jump off of the Hollywood Sign after her wedding does not go as planned. Grey responds that if that is true, nothing Grey puts Nolan through will deter him. Nolan tells Grey that he believes being a cop might be his calling. Grey informs Nolan that he will do everything in his power to discourage him from continuing to serve, as he fears that Nolan's inexperience and age will endanger the lives of his officers. Also joining Nolan as rookie officers are Jackson West, son of a high-ranking LAPD officer and eager to live up to the family legacy, and Lucy Chen, who became a cop against the wishes of her therapist parents and is carrying on a secret affair with Nolan despite the risk it poses to her career. Nolan's first few days on the job are marked by a domestic dispute that quickly escalates out of hand (during which Nolan witnesses his first death), an unbalanced father who leaves his child in a locked car on a hot day, and an escaped felon who quickly tests Nolan in ways he never expected. His assignment to the force, particularly the Mid-Wiltshire Division of the LAPD is met with skepticism from his fellow officers, particularly his watch commander, Sergeant Wade Grey, and his training officer Talia Bishop.

Nine months after witnessing (and foiling) a bank robbery in his small town of Foxburg, Pennsylvania, John Nolan, a 45 year old divorcé packs up his entire life to move to Los Angeles and becomes a cop.
