Hamberger is a freelance private eye without a license and without a car, who hangs out at delis looking for potential work.
He is approached by a businessman claiming to be Alex Burton who offers him $100,000 to kill his wife Sharon who knows too much about his business dealings.
Hamberger accepts a down payment of $25,000 but instead decides to inform Sharon of the plot and helps her flee by plane.
Hamberger uncovers a heroin distribution operation through a link to a modeling agency and seeks to find the real killer before the police take him in for a crime he did not commit.
Filming took place at Rockefeller Center, Times Square in Manhattan and at Shea Stadium in Queens.
