Using the alias Stephen Fitzgerald, con artist Andrew Cook (James Daly) has married the widow of a bank owner, embezzled the bank funds, and murdered his wife--a pattern he has followed for years in several other cities. Now the homicidal Cook has targeted wealthy Amy Hunter (Margaret Leighton) as his next victim, with both Amy's life and a million-dollar "prize" at stake. Inspector Erskine (Efrem Zimbalist Jr.) must figure out the reason behind Fitzgerald's modus operandi in order to stop him before he can steal--and kill--again.
