Continuing six months after Death Wish left off, Paul Benjamin has moved from New York to Chicago after his catatonic daughter died in an institution, a result of the brutal attack that changed Paul Benjamin into a vigilante. Paul resumes his private violent war as he stalks criminals in the streets of Chicago. The only thing that may distract him from his crusade is a beautiful woman he starts cordially dating in his new life. And as Paul ends up having a double life, an imitating vigilante is out in the streets violently killing off criminals just like Paul. What's worse is that vigilantism soon begins to become a cry of publicity as the police have to look for their man before innocent people start dying out of injustice. Paul is not only after criminals or justice anymore, but he's also looking for a man who is as equally as dangerous as the vigilante he has become.
In 2007, a film based on the novel (though a completely different storyline) was made, starring Kevin Bacon and directed by James Wan.
