The movie depicts a future in which all plant life on Earth has been made extinct, and only a few specimens have been preserved in large, greenhouse-like domes attached to a fleet of Space Freighters positioned just outside the orbit of Saturn. The Valley Forge is one of the 2,000 foot-long freighters.

When orders come from Earth to jettison and destroy the domes and return the freighters to commercial service, Lowell opts instead to save the last remaining forests in existence.

Hailed as one of the best science-fiction movies of the 1970s, Silent Running is a unique movie that conveys a serious ecological message in an unforgettable manner.
