Billionaire Jordan Braddock is given blood after a plane crash. The blood came from an employee in Braddock's vast empire, a test car driver by the name of Ben Richards. Because the old man recovers and grows younger
, the doctor performs tests on Ben's blood and discovers that Ben is immune from all diseases, and even from aging. "You're practically immortal," the doctor tells Ben. As the effects of Ben's blood begin to wear off and Braddock begins to age and grow ill again, he realizes that he must keep Ben nearby as a personal fountain of youth, so he devises a plot to kidnap the test driver and fake his death so no one will look for him.
