Lowell Freeman looks after plants in giant space greenhouses. Back on earth, all the trees have long vanished, so Lowell puts a lot of heart into his work. When orders from earth are received to destroy the greenhouses, Lowell can't go through with it, and cannot persuade his three colleagues to help him save the plants, so he makes other "arrangements". The loner crew member of a spaceship harbouring Earth's last nature reserves goes renegade when he is instructed to jettison his beloved forests and return home. Accompanied only by three robots, he ponders the fate of his last pocket of nature and the murders of his fellow crew members in this far-looking speculative film.
