Sledge Hammer! - Season 2 Episode 8

The FBI has learned that mobster Clive Winston is planning a prison break. They recruit Hammer to go undercover, because they don't want to risk of their own men. Hammer, pretending to be a famous hitman, gets put into the same cell as Winston. Winston does not like him at first. However, when one of the inmates recognizes Hammer and tries to kill him, Winston mistakenly thinks he was the target, and that Sledge saved his life. He then lets Hammer in on the breakout plan.
