Investigators initially rule the death a suicide, but Captain Ed Hocken isn't convinced that a boxer would kill himself right after the biggest win of his career.

Believing that they are dealing with murder and corruption, Ed decides to send Frank Drebin undercover.

They allow Frank to join the game and the stakes begin to climb, with the pot growing to include cash, gold, gems, Monopoly playing pieces—and eventually Buddy Briggs' contract.

The hair belongs to Luca Burnett, the man who killed Mike Schultz, and a known associate of Martin.

She claims that Martin and Cooper "own him" and storms out of the apartment, returning briefly to get her St. Bernard named "Muffin".

Frank promises to help Buddy fight fair and win, claiming that he and Mary have been living in the sewers too long.

Buddy and Frank decide to meet at Morey's Bar in the evening, to arrange a fight with "The Champ", who is managed by Cooper and Martin.

He threatens her safety unless Buddy "takes a dive" in the 12th round, and shows him Mary's toaster to prove he's not bluffing.

Johnny tells Frank that Mary is being held hostage by Luca Burnett at Jim's Gym.
