Mission: Impossible - Season 7 Episode 17 : The Fountain 1973

Syndicate exec Tom Bachman has stolen the computerized records from his rival Matthew Drake in a power struggle. Bachman is hiding in a village in Mexico from the crippled Drake, waiting for a hired pilot to take him to safety. Barney takes the pilot's place and then fakes a crash where he and Bachman stumble across the ""Fellowship of the Golden Circle."" Bachman discovers they have a fountain of youth - when Drake's men catch up to him, he takes Casey along as proof of his claim and offers to return the records if Drake backs him in distributing the water. Casey ages and dies before their eyes, and Drake agrees so he can get a shot at the water's healing properties. Bachman leads Drake (and the IMF) to the hidden tapes and the crooks gets arrested.
