Under the leadership of Tarrant (Steven Pacey), the Liberator crew steals the Kairopan crystal harvest, which would otherwise be used for the Federation's weaponry. Unfortunately, Servalan (Jacqueline Pearce) and her Federation minions have managed to board the disabled Liberator, leaving the crew stranded on Kairos, now a dangerous place, indeed. The fate of the good guys may well rest with the ship's computer, Zen -- but only if Servalan is unable to corrupt Zen's memory banks. "The Harvest of Kairos" first aired on February 4, 1980. ~ Hal Erickson, Rovi
