S7·E18 The Fighter

Syndicate man Jay Braddock has corrupted promoter Paul Mitchell into working with him - they had middleweighter Loomis killed when he refused to throw a fight and the IMF must bring both men to justice. They do so by convincing Mitchell that his partner plans to kill him. Barney and Jim steal $37,800 from Braddock and then as a rival mob offer the partners the same amount to buy out their fighter Novick. Braddock decides to have Novick killed but the IMF intercept the call and send in Jim as the hit man. He ""kills"" Novick with a firebomb along with Susan Mitchell (actually Casey in disugise), the promoter's daughter. Mitchell tries to back out as the IMF pressure him, but Braddock messes things up by offering to kill Jim to reassure Mitchell. He manages to escape and they arrest both men.
