Dangerous obsessions take center stage when a former assassin and a homicide detective race against the clock to find a missing girl before she's sold to the highest bidder. Identified as a person of interest in three cold case murders she didn't commit and required to stay in L.A., retired assassin Leine Basso accepts a temporary position as a security specialist for A-list actor Miles Fournier. Soon, a woman contacts Miles, claiming to be his long-lost sister. Her twelve-year-old daughter, Mara, has been abducted and she's desperate to get her back. Leine learns from a contact that Mara escaped, but the traffickers are determined to track her down and deliver her to their powerful client. Running out of time, Leine must find Mara before they do, or she will be lost forever.
