The week-long national syndication window opens for the 72nd episode of Star Trek: Deep Space Nine. This two-hour episode opens the fourth season of the series. Star Trek: The Next Generation regular Michael Dorn joins the DS9 cast as Worf, newly transferred to the station. J.G. Hertzler makes his first appearance as General Martok; Andrew Robionson and Patricia Tallman (Babylon 5) guest star. 
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.
