Where's Dad?

Gavin Johnson took in three girls and raised them as his own daughters through hard years. The three grew up to work on a project for extending human life, the Life Extension Project. Another man's scheming came between Gavin and the sisters, and the three turned on him and cut him off. Gavin lost heart. He chose to enter a sleep capsule and go into hibernation, so that what remained of his life would go to the daughters' project as his last contribution to it. Years later he met Anya Anderson, his biological daughter, and recognised her. The three sisters were in a car accident, and after it they too were put into hibernation under the Life Extension Project.
