DS9 Season 6 Episode 10 The Magnificent Ferengi

Plot

Quark learns that his mother, Ishka, has been captured by the Dominion. The Ferengi leader Grand Nagus Zek (who is also Ishka's lover) offers a reward of 50 bars of gold-pressed latinum for her rescue. Quark and his brother Rom decide to assemble an all-Ferengi commando team to rescue her, claiming that the reward is 20 bars so they can keep a larger share. They first recruit Rom's son Nog, making him "Strategic Operations Officer" for the mission. Next, they hire Leck, a Ferengi "eliminator", tempting him with the challenge of fighting the Dominion's Jem'Hadar soldiers. Quark bails out his cousin Gaila, who has been arrested for vagrancy, and signs him up as a chance for redemption. Disgraced ex-Liquidator Brunt, hoping to win Zek's favor, persuades them to add him to the team for the use of his ship.
In battle-training simulations, the Ferengi prove to be poor commandos; one simulation ends with Leck killing Ishka. Quark and Rom realize that although Ferengi may not be good commandos, they are excellent negotiators; instead of attacking the Dominion, they propose a prisoner exchange to win Ishka's freedom. Deep Space Nine's senior officers give Quark custody of Keevan, one of the Dominion's Vorta commanders captured in the episode Rocks and Shoals, and Quark arranges a meeting with the Dominion at the abandoned Cardassian space station Empok Nor.
The team makes base camp in Empok Nor's infirmary. The Dominion's negotiator, a Vorta named Yelgrun, arrives with Ishka in custody, guarded by a squad of Jem'Hadar. Quark offers his terms, to which Yelgrun agrees: all but two Jem'Hadar must leave the station before the prisoner exchange takes place. While celebrating their soon-to-be-successful exchange, Rom accidentally lets slip that the reward is actually 50 bars, not 20. In a rage, Gaila tries to shoot Quark but ends up killing Keevan.
Quark persuades the team not to give up, offering equal shares of the 50 bars. Nog discovers some working neural stimulators in the abandoned infirmary, which enables him to move Keevan's body by remote control. At the prisoner exchange, they are able to get Keevan's dead body to walk; Yelgrun does not realize he is dead until after Ishka is safely with Quark, when Keevan walks into a bulkhead. The Ferengi ambush the two Jem'Hadar guards and capture Yelgrun; as they leave Empok Nor, Keevan's body continues walking into the bulkhead.
