Adultery pays. Murder doesn't. That is P.I. Nate 'Nasty' Jepson's motto, and he normally makes his living snapping pictures of cheating spouses. When a stranger is brutally shot in the passenger seat of his car, he finds himself in the middle of a gang war between battling triads, as well as a suspect in the murder. Nate must step far outside his comfort zone to clear himself and live to catch another cheater.
