Devil's corner

Prosecutor Vicki Allegretti goes to meet a confidential informant, is almost killed, and a cop is gunned down before her eyes. She saw the killers, now all she has to do is find them. The deeper Vicki probes, the more she becomes convinced that the murder wasn't random. When another murder takes place, Vicki is thrown together with an unlikely ally — The Girlfriend from Hell. Will they find the killers before they kill each other?
