The Final Patient (2005)

When retired physician Daniel Green (Bill Cobbs, Night at the Museum) lifts a 5-ton farm tractor off a boy trapped beneath, the enigma of his supernatural strength piques the curiosity of two med students passing through town. Visiting the old doctor at his isolated farmhouse, they soon learn his bizarre secret: he has uncovered the key to eternal youth. But sometimes the lust for immortality has deadly consequences. The night takes a twisted turn as the young men discover Dr. Green's "miracle" has come with a horrifying price - and a fate far worse than growing old.
