Mission: Impossible - Season 6 Episode 6 : The Miracle 1973

Only two Syndicate men know where $8 mil in heroin will be arriving - narcotics dealer Alvin Taylor an dhis executioner, Frank Kearney. When Jim approaches Kearney to make a deal and he refuses, Willie ""shoots"" Kearney - Barney as a surgeon then operates providing a heart transplant and covertly uses drugs and hypnotism to make Kearney mild-mannered. Kearney can't bring himself to shoot Jim and hears on the radio about people taking on the traits of persons they received organs from - with the aid of new girlfriend, the church-hating Kearney finds out the man who donated a heart was a priest! Realizing he can't do his job and the Syndicate will wipe him out, Kearney leads Casey and the rest of the team to the beach where the heroin drop occurs, and the police arrive just before Taynor can kill Kearney.
