Sture Lundblad was a Swedish volunteer fighter in the Spanish civil war. Sture is now dead. His son Michael has inherited a house in Spain and decides to follow the trail of his father.

The theft of a fortune in diamonds and the attempt by soldier of fortune Johnny Dent to outwit his pursuers who would stop at nothing to get their hands on the treasure forms the story-line. The chase reaches across the continent as Dent eludes the diamond syndicate police, a ruthless gangster, and a scheming girl in his attempt to escape.
