Tales from the Darkside - Season 2 Episode 2 Lifebomb

Ben Martin, a rich businessman, is contacted by a special medical firm, "Lifebomb" which offers him an expensive policy that will let him live forever. They give him an implanted device which, every time he "dies," activates and places him in a cocoon until the corporation can arrive and revive him. His wife soon leaves him and since Ben is close to death, the Lifebomb goes off constantly. Tired of life, he finds that he is trapped since Lifebomb refuses to call off the policy so that they can make money off of him.
