Officer Nolan (Nathan Fillion) sustains some mild injuries while chasing down a shoplifter in the Season 3 finale "Threshold." Afterwards, Nolan doesn't see any point in making an issue of getting slightly hurt, but the overzealous district attorney decides to charge the suspect with assault. Elsewhere, Lucy (Melissa O'Neil) goes undercover, while Lopez's (Alyssa Diaz) wedding venue is seized by the FBI. Back on the homefront, Nolan meets his new neighbor. Camille Guaty, Dylan Conrique, Jane Daly, Nik Sanchez and Britni Camacho guest star.
