The detectives of Southwest 101 investigate the murder of a female backpacker. Cameron's new lover accuses her partner, Guido Martin, of stealing money while working undercover. The man has first hand experience—he's a hitman.

Guido's undercover past threatens his job at Southwest 101 when he becomes the prime suspect in the murder of Vincent Rinaldi, a crime figure Guido was involved with while working undercover and whose $2 million he is now being accused of stealing. As his colleagues' trust in him is put to the test, Guido's sole focus is on locating a missing 18-year-old girl, leaving him at risk of sacrificing everything for a girl he has never even met.
