Crime is rampant in the city; gangs of young thugs attack families at random. Because of this, Victor is working on a project to electro-shock violent criminals. By using this therapy he hopes to turn them into model citizens. Recently, there has been a rash of unresolved killings, the victims are always young men. These slayings have been attributed to a serial killer, probably a sadistic homosexual. But it is Anna who is the perpetrator.

Things become complicated when David, a former gang member witnesses her execute a young man. He begins to extort money in exchange for his silence.
