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.
