Multi-generational starship Earthship Ark, containing dozens of biospheres, suffered an emergency hundreds of years ago. Now one man is challenging the existing order. This legendary Canadian sci-fi series brought together the talents of Harlan Ellison and Douglas Trumbull, as well as acting greats Walter Koenig (Star Trek's Checkov), Keir Dullea (2001: A Space Odyssey), Alexandra Bastedo (The Champions) and Sterling Hayden. The production was famously problematic, causing Ellison to withdraw his involvement and name, but the series has acquired a cult following since. This is the movie-reedit.
