The 1952 film "Kansas City Confidential" is a crime drama set first in Kansas City, Missouri, and then at a Mexican resort. "Mr. Big" organizes a bank robbery of over $1,000,000 in cash with three men, none of whom know each other or who the mastermind is as they all wear masks when they meet. Joe Rolfe, an ex-convict working as a florist deliveryman, is arrested for the robbery as his work truck resembles one used by the robbers. He is later released and decides that the only way to clear himself is to find the real perpetrators. With the help of a friend who has contacts in the underworld, Joe travels to Mexico, impersonates one member of the gang, and survives a shootout between the gang members over the loot. One scene set in a Mexican gambling casino shows prop coins on a dice table. The prop coins are the President Monroe motion picture prop coins which are used in many films.

The film opens with a prologue:

The first scene is of the Kansas City skyline in 1952.

Next viewers get to meet "Mr. Big."

"Mr. Big", wearing a mask, talks to one of the three members of his robbery gang. Unknown to the gang members, he is an ex-police captain.

The well planned robbery succeeds and the masked robbers get $1,200,000 in cash. Mr. Big then meets with his crew.

As the members do not know each other (except for the main man), he hands out torn halves of playing cards to the members for use in future meetings. Joe Rolfe, an ex-convict who drives a truck similar to one that the robbers used, is arrested.

The "third degree" is a slang term for a harsh police interrogation of a suspect. Joe is released but due to the arrest loses his job. He decides that the only way to clear himself is to find the real criminals. A friend who has underworld contacts tells him that a wanted gambler named Pete Harris suddenly had some money and travelled to Mexico. Joe heads for Tiajuana, Mexico to search casinos for the gambler.

The coins on the table are Los Angeles Rubber Stamp Company President Monroe prop coins.
