At Space City, Blake (Gareth Thomas) must negotiate with the criminal organization Terra Nostra in order to destroy the Federation. Mob leader Largo (Derek Smith) doesn't take a shine to Blake, and as a result the crew is imprisoned. Back on the Liberator, Cally issues a threat to Largo, stating that she will destroy Space City if her comrades are not immediately released. Things become more complicated when the supercomputer Orac is subjected to a hostile takeover by an unknown power. "Shadow" was first broadcast on January 16, 1979. ~ Hal Erickson, Rovi
