DS9 Season 5 Episode 2 The Ship

Plot

An away-team of Deep Space Nine crew, led by Captain Benjamin Sisko, are conducting a mineral survey on an uninhabited Gamma Quadrant planet, while their runabout awaits them in orbit. A Dominion warship crashes near their location; investigating, they find the crew dead. Sisko contacts DS9 to have the USS Defiant come tow the ship back to the station so that it can be studied.
Another Dominion ship arrives, destroys the runabout and its crew, and transports a number of Jem'Hadar soldiers to the surface along with their Vorta supervisor, Kilana. The soldiers fire on the away-team, killing one and wounding Muñiz, an assistant to chief engineer O'Brien. Sisko's crew flees into the crashed ship for protection. Muñiz begins slowly bleeding to death as a result of his injury.
Kilana meets with Sisko, offering to return the away team safely to DS9 if they yield the ship. Meanwhile, a Jem'Hadar transports onto the crashed ship and attacks the team; Muñiz, though weakened, is able to shoot the Jem'Hadar. Kilana and Sisko immediately return to their ships. Sisko deduces that there is something valuable aboard that they are unwilling to risk damaging in a direct attack. He rejects a new offer from Kilana to allow Sisko to keep the ship if he permits the Jem'Hadar to retrieve an item from it.
O'Brien tries to assure a now delirious Muñiz that he will live, but Lt. Cmdr Worf asserts that Muñiz should be prepared for death. Tempers flare and a fight almost breaks out. Sisko sternly orders the crew to pull themselves together. O'Brien's attempt to bring the ship's engines online fails, and Muñiz dies.
The ship's precious cargo finally reveals itself: a dying Changeling, one of the Founders of the Dominion whom the Jem'Hadar and Vorta revere as gods. After it dies, Kilana transports to the vessel. She explains that her Jem'Hadar have committed suicide for allowing the death of a Founder, and there is no further reason to prevent Starfleet from salvaging the ship. Sisko allows her to collect some of the Changeling's remains before she leaves.
The Defiant eventually arrives and tows the ship back to DS9. O'Brien and Worf hold a vigil over Muñiz's casket. Sisko tries to write a report for Starfleet, but keeps lingering on the five crewmen who died on the mission. Despite knowing the ship's recovery could save thousands of lives, Sisko still feels they deserved more than to die on an isolated planet so far from home.
