“In a society where justice has long been lost, all it takes is a single phone call to set things right.” A mysterious taxi service delivers vengeance on behalf of victims who have been failed by the law, imprisoning the perpetrators in their own hidden prison. But when a determined prosecutor begins to notice that the criminals she has been pursuing are mysteriously disappearing, a dangerous game of cat and mouse unfolds between her and the vigilantes behind the taxi service. The simple mission to punish evil and restore justice soon forces the group to confront a troubling question: Is revenge truly a form of justice, or is it simply another crime? As the lines between right and wrong begin to blur, the dark heroes find themselves caught in a spiral of consequences that threatens to unravel everything they believe in.
