The Spindrift, a commercial spaceship on a flight from New York City to London, became lost when it passed through a time warp in its orbit around Earth. It landed on an alternate Earth-type planet, where the inhabitants were roughly twelve times the size of its passengers.
Our heroes include Steve Burton, the captain; Dan, the copilot; Betty, the stewardess; Mark, an arrogant engineer; Valerie, a sexy jet-setter; Barry, a young boy; his dog, Chipper; and Commander Fitzhugh, a mysterious rogue. Together they battle the planet's totalitarian government, try to avoid capture, and attempt to repair the ship so they can get back home.
