When Detective Christine Rollins receives a frantic phone call from her younger brother asking for help, she assumes he's gotten himself into some kind of legal trouble again. But when he doesn't show up to meet her, she fears the worst. Not knowing what her brother was caught up in and hoping to avoid LAPD involvement, she turns to Sam and Eddie to help track him down. But when surveillance video shows Tyler stealing a luxury car, Christine learns that her once-wayward younger brother is back to his old ways and may be tied to something even worse. Meanwhile, Sam is dealing with family drama of her own.
Sam Swift is the former star of a hit cop series who's fresh-out-of-rehab following a bender of epic proportion. Desperate to restart her career, she talks her way into shadowing rough-and-tumble private investigator Eddie as research for a potential comeback role.
Though lonewolf Eddie resents the babysitting gig, high-spirited Sam proves herself to be surprisingly valuable, drawing on her acting skills and 200 episodes of playing a detective. When the press touts Sam's role in solving a high-profile case, Eddie finds his phone ringing off the hook with new clients looking to hire the pair.
