A woman is held at the airport whose documents say that she's Mrs. Mike Hammer. She's a foreigner who claimed to be his wife so that she could get into the country quietly. She says that her country is trying to change things and is in New York to collect money intended for the reform. When someone tries to kill her, Mike kills him but without her testimony, it can't be proven that it was justified, and she's about to be deported. So Mike marries her.

A woman in distress appears in Hammer's office asking for his help. It turns out to be his daughter, a woman that he didn't know existed. She is a singer in a band and the money she is raising for a charity is disappearing.
