Follow That Woman is a 1945 American comedy crime film directed by Lew Landers and starring William Gargan, Nancy Kelly and Regis Toomey.

Nancy witnesses what she believes is a holdup at the very next table, and instinctively she hits the gunman over the head with a champagne bottle, knocking him out completely.

The gunman, Sam Boone, is really an undercover police officer posing as a gangster, who was trying to make an arrest when Nancy hit him.

Afraid that a scandal and his association with a murder might spoil his chances of entering into an Army training program he has been accepted to, Sam decides to ignore the lead and not mention that he was ever in the dressing room.

They leave, and Sam asks Nick, the nightclub host, not to tell the police he was the one who found Marge's dead body.

One day Nancy and Butch get a phone call from a man named J.B. Henderson, who wants to hire a detective to find Marge Andrews.

Butch sends a letter to Sam at the Army camp, asking him to leave his duty, to come back home and convince his wife that she should stop playing private detective.

Sam goes to Henderson and finds out that Marge had a few more men around her, including a college student by the name of John Evans.
