Ray and Frank are the only survivors of the Jersey Queen, an independent freighter hit by (space!) pirates. In the chaos, the doomed ship took a blind jump through the hyperways, leaving them stranded in a dark and lonely quadrant of space.
Mikey and Gerard are the last remaining crew of a legendary "ghost" ship, the Ravenkroft which has been lost for the fifty years since the War that Broke the Stations. They've been avoiding inhabited space due to emotional scarring from the loss of their crew, and a feeling of isolation due to the fact that they are in fact cyborgs.
They pick up Ray and Frank's escape pod, and promise to help them. In the process, old feelings of guilt are assuaged, new emotional ties are wrought, and the legendary ship comes home.
