Irwin Allen's Lost in Space

The Robinson family was supposed to set off on a five-year mission to explore a distant planet, but an act of sabotage by the scheming Dr. Zachary Smith - who managed to get himself trapped aboard the spaceship - leaves them adrift in space for three years. The Robinsons, pilot Don West, Dr. Smith and their trusty robot move from planet to planet, always searching for a way to return to Earth.
