A young girl is framed for a robbery and sent to a harsh reform school, where she becomes the target of a vicious warden.

A man tries to burgle his own safe on the same night that a professional criminal attempts it.

Someone is stealing priceless paintings from the great museums of the world and replacing them with nearly flawless forgeries. Leonardo da Vinci's "Madonna and Child" is being shipped to London's Tate Gallery for a special exhibition, and Paul Mitchell is assigned to protect it.
