A colossal computer - the "colossus" of the title - goes online, taking complete control of the country's national defense. Almost immediately, it develops a mind of its own, hooks up with its Soviet counterpart, and makes demands that become increasingly paranoid and alarming. Far-fetched but provocative sci-fi, a variation on the HAL-9000 segment in "2001". The chronically underused Susan Clark plays a scientist who poses as Eric Braedon's love interest.
