Starfleet Command decides to take the offensive in the war against the Dominion, and Sisko is chosen to lead the invasion of Cardassia. The first target is the Chin'toka System, picked for its diminished defenses. Unfortunately, the crew is unaware that the Cardassian/Dominion Alliance has secretly deployed hundreds of orbital weapon platforms to protect system, and that Gul Dukat has returned claiming he has the key to destroying Sisko and the Federation.
