DS9 Season 2 Episode 26 The Jem’Hadar

Plot

Commander Sisko and his son Jake are preparing for a father-son camping trip to a planet in the Gamma Quadrant. Sisko is disappointed when Jake invites his best friend Nog to join them, and even more dismayed when Nog's uncle Quark invites himself along as well. They depart as planned, but as they set up camp, Quark quickly becomes irritated by the environment and argues with Sisko, leading an embarrassed Nog to storm off into the woods with Jake chasing after him.
Sisko and Quark are startled when an alien woman comes running out of the forest, pursued by a troop of fierce soldiers, who take all three captive. Sisko, Quark, and the woman, Eris, are taken to a cave where they are imprisoned in a force field. Eris warns Sisko that the field is lethal, and that she is unable to use her telekinetic abilities to disable it due to the suppressive collar around her neck. She explains that the soldiers are Jem'Hadar, bred and put into service by the Dominion, who rule that section of the Gamma Quadrant, and that they cannot be escaped or defeated. Sisko points out that they have been imprisoned together and are not under close guard, believing that he can use their captors' apparent overconfidence to their advantage, and begins by attempting to remove Eris' collar.
Third Talak'talan, leader of the Jem'Hadar group, informs Sisko that the Dominion will no longer tolerate the presence of ships from the other side of the wormhole and reveals extensive knowledge of the Alpha Quadrant, but he refuses to allow Sisko to speak with the Founders, leaders of the Dominion, whom Eris then claims are a myth. After several hours, Sisko makes some progress on removing Eris' collar and enlists Quark to pick the lock.
Meanwhile, Jake and Nog, having returned to camp to find Sisko and Quark gone, locate the Jem'Hadar encampment. They return to the runabout but are unable to beam the captives off the planet or bypass the ship's autopilot to break orbit in order to get help. When they finally gain control of the ship, they realize that without the autopilot, they will have to learn to pilot it themselves.
Back on DS9, a ship arrives unexpectedly through the wormhole, and Talak'talan suddenly materializes in Ops, despite the station's shields being raised. He informs the crew that Sisko is being detained by the Dominion, then transports away before he can be caught, walking unaffected through a security forcefield. Captain Keogh, in command of the Galaxy-class starship U.S.S. Odyssey arrives at the station to assess the situation and mount a rescue mission. He allows the station's two remaining runabouts, crewed by Major Kira, O'Brien, Dax, Odo, and Dr. Bashir, to accompany the Odyssey on its mission.
Quark manages to remove Eris' collar, allowing her to disengage the force field, and the three escape. Meanwhile, the Federation ships come under attack, with the Odyssey sustaining heavy damage, as the Jem'Hadar weapons are able to bypass its shields. O'Brien beams aboard Jake and Nog's runabout and takes control, then beams aboard Sisko, Quark, and Eris. As the group begins to retreat to the Alpha Quadrant, one of the Jem'Hadar ships makes a suicide run at the Odyssey, colliding with it and destroying it almost instantly. Back at the station, Quark discovers Eris' collar is a fake, and they deduce that she is a spy for the Dominion, which she admits before transporting away — leaving the crew with the realization that their dealings with this powerful new opponent have only begun.
