Sisko and former Cardassian leader Gul Dukat, who is a prisoner and awaiting trial for war crimes, are marooned together on a deserted planet, and Sisko must rely on the increasingly unstable Dukat for his survival.

The USS Honshu is transporting Gul Dukat to his war crimes investigation. Sisko is also onboard and goes to see the former Cardassian leader who is being held in the ship's brig. Dukat, who suffered a nervous breakdown over the death of his daughter, assures Sisko that he has recovered. Suddenly, the ship is ambushed by Cardassian warships. During the attack Sisko is seriously injured, but Dukat, who is released from his cell, is able to get him to a shuttlecraft. They manage to escape to a nearby planet where he tends to Sisko's wounds. When Sisko regains consciousness, Dukat informs him that they are stranded and he is sending out a distress signal.

Unbeknownst to Sisko, Dukat hallucinates encounters with Weyoun and Damar, who advise him to kill the Starfleet captain. Dukat reveals that he intends to — after Sisko shows him the respect he deserves. While Dukat "talks" with his colleagues, Sisko notices that the communications system is, in fact, not sending out a signal. When Dukat returns, Sisko tests him by asking him to check the system. He does, telling Sisko the unit is working fine.

Meanwhile, Worf searches for Sisko in the Defiant, but has limited time before he must leave to escort a convoy of Federation ships. Sisko adjusts the communications system while Dukat is out, but must stop when he returns and "play along" while Dukat defends his treatment of the Bajorans. When Dukat starts "arguing" with Kira, Sisko realizes something is very wrong. He pretends to agree with Dukat, and the ruse almost works until Dukat notices that the distress signal is now on-line. He destroys the com system and attacks the defenseless Sisko.
