Approaching Cephlon, the Liberator crew witness a spacecraft crash land on the planet. They rescue a man named Ensor, who was trying to get back to his father on Aristo and arrange for the Federation to purchase something called Orac. He forces Blake and Cally to fly him to Aristo, leaving Avon, Jenna, Gan, and Vila stranded on the radiation-scarred surface of Cephlon.
