Stardate 49011.4: As the crew of Deep Space 9 try to prepare for a possible invasion
by the Dominion, a fleet of Klingon
ships decloak and take
"shore leave" on the station. The
Cardassians have sealed their borders after a rumored
coup on their homeworld, and Klingon ships are
stopping ships leaving Bajoran space to search them
for Changelings. To get answers, Sisko calls on the aid of Lt. Commander Worf, who has been among the Klingon clerics
on Boreth following the Enterprise's destruction, and is considering
resigning Starfleet. Worf learns that the Klingons
plan to invade Cardassia on the suspicion that the
new civilian government is run by the Founders. Sisko
uses Garak to warn the Cardassians, and Gul Dukat
manages to save the Detepa Council as the Klingon
fleet advances. But the Defiant is needed to get them to safety - and
its aid will have far-reaching consequences for the
Federation and the Klingon Empire.
