Kevin is a derivatives trader in a New York investment bank. He leads a quiet, even boring life, but all of this changes after he meets an attractive young woman at a conference. First his boss and then a co-worker are murdered, and Kevin starts to realize that all is not right with the woman with whom he is falling in love. Unfortunately for Kevin, he has taken advantage of the incompetence of the firm's accounting staff in order to inflate the profits of his desk, and his petty crime now threatens to embroil him in the murders that are happening around him. When it turns out that an enormous amount of money has been embezzled from one of the books he is trading, he decides to find the murderer before the police finds out about him.
