At the edge of the galaxy, Liberator nearly collides with a Federation freighter. Blake is curious to know why the ship is so far from home and decides to follow it to a mysterious planet called Horizon. Teleporting down, Blake and Jenna discover a secret mining operation and are captured for interrogation. Gan and Vila go down to find them but are captured as well. All are forced to work in a dangerous mine while Blake tries to urge Ro, the planet's leader, that the Federation is manipulating him and enslaving his people. Meanwhile Avon considers taking the Liberator and leaving them all behind, but Cally won't hear of it and goes down to find the others. Avon asks Orac what his chances are of surviving against the Federation alone.
