When his vicious cousin Alejandro makes a violent late-night visit, San Diego homicide detective Ray Delgado gets a brutal reminder of why he left his family behind. Alejandro wants Ray to find his sister, Sophia, who disappeared from the UC San Diego campus, before the FBI digs too deep into his business.

Special Agent Elliot Belkamp spent his entire life jumping from one place to another, but his new assignment assisting a FBI task force offers him a chance to settle down. When Elliot catches a missing person's case as his first assignment, the last person he expects to find poking around the victim's dorm room is Ray, a one-time hookup he's more inclined to punch in the face than kiss hello. After discovering Sophia's disappearance is linked to a massive computer-based theft that has two powerful crime families ready to declare war, Elliot focuses on his investigation and tries to ignore Ray. As the search for Sophia turns dangerous, Elliot and Ray discover that tackling organized crime might be easier than resisting the urge to tackle each other.
