Summary:	As the Dominion threat to the Alpha quadrant increases, the peace treaty between the Klingon Empire and the Federation is in jeopardy. Captain Sisko has requested that Lieutenant Commander Worf (Michael Dorn) come to Deep Space Nine to act as a diplomatic liaison with the Klingons. When the Federation condemns the Klingon invasion of Cardassia, the Klingon Empire withdraws from their peace treaty with the Federation. Gowron offers Worf the chance to redeem himself by joining his people in the assault on Cardassia. Worf declines, prompting Gowron to excommunicate Worf's entire family. Worf then attempts to resign from Starfleet, but Sisko refuses to accept his resignation. After offering to aid the Cardassians, Sisko and the crew prepare for battle with the Klingon fleet.
