The Way of the Warrior

When the Klingon Empire withdraws from its peace treaty with the Federation, Sisko must help Klingon Starfleet officer Worf decide where his loyalties lie. Gowron excommunicates Worf's entire family, and Sisko refuses to accept his resignation from Starfleet at this critical time. Agreeing to escort the Cardassian ruling council out of the war zone, Sisko, Worf, Dax, and Bashir take the Defiant to a rendezvous point, where Dukat's ship is under heavy fire. The Defiant decloaks and prepares to attack the Klingons, ending two decades of peace.
