Synopsis by Hal Erickson
After rescuing Jenna (Sally Knyvette) from the hostile natives of Cephelon, Blake (Gareth Thomas) must evade Servalan (Jacqueline Pearce) long enough to deliver much-needed medical supplies to the scientist Ensor (Derek Farr) on the planet Aristo. Alas, Blake is too late: Ensor has died. Fortunately, Blake and his comrades have "inherited" Ensor's high-tech computer Orac, which -- less fortunately -- serves up a future vision showing the utter destruction of the Liberator and its crew. And on this "cliffhanger" note, the first season of Blakes 7 draws to a close. "Orac" originally aired on March 27, 1978.
