Kansas City Confidential

A former detective (Foster) devises a perfect armored-car robbery. However, in order for him to pull it off successfully, he blackmails three criminals (Van Cleef, Elam, and Brand) with incriminating evidence from other "jobs". Each of the perpetrators are forced to wear masks, thus concealing their identities from one another and preventing the men from squealing and backstabbing. Everything is going according to plan but a complication arises when the police arrest a man (Rolfe) who happens to drive a van similar to the one used in the robbery. Vowing revenge, this man sets out to find the real criminals and clear his name.
