Malibu Comics' miniseries sees the cast of Star Trek: Deep Space Nine caught in the middle of a difficult conflict.
A Klingon cruiser disappears without a trace and the prime suspects are the Cardassians. Thirsty for revenge, the Klingons call for the aid of their allies: the Federation.
Captain Sisko and the crew of Deep Space Nine find themselves in a tricky position. Their main goal is to advocate peace between Bajor and Cardassia Prime, but they must also act on the Klingons' request.
