Director:	Douglas Trumbull
Actors:	Ron Rifkin, Bruce Dern, Jesse Vint, Cliff Potts

As this science fiction classic opens, botanist Freeman Lowell (Bruce Derns) has spent three years aboard the space freighter "Valley Forge" preserving the only botanical specimens left on earth under huge Geodesic domes. When he receives orders to destroy the project and return home Lowell rebels and hijacks the freighter, killing his fellow crewmen, injuring himself, and plunging the craft into the gaseous rings of Saturn. From that moment on, he has only the trees, the gardens, and two "Drone" robots, Huey and Dewey, to keep him company on the loneliest adventure of all.
