A deadly teen rivalry. A scorned lover willing to kill. A quick-rich scheme gone bad. The true-life mysteries detailed in this series are about revenge, betrayal and murder carried out by the people seemingly most trusted by each of the victims -- their lovers. The cases, dramatized via re-enactments, focus on the criminal's motive, and explore how the victim and lover met, the deepening relationship, the perceived betrayal and the obsession that led to the deadly act. Each hourlong episode takes viewers though all of the twists and turns that culminate in arrests, verdicts and justice.
