The Federation has encouraged its starships to participate in an "exchange" program. As part of a multi-cultural thing, a group of aliens comes on board the Enterprise. They are eager, and one in particular, a Benzite, like the one who beat Wesley out of a position at the Academy, becomes a bit of a nuisance. A combination of scientific ability and sycophancy make this character intriguing. Like his predecessor, his existence requires him to breath vapors emanating from a tray under his chin. When Picard talks to Number One, asking if he could suggest a crewman to go on board a Klingon ship for the exchange, Riker quickly jumps at the chance. Worf helps prepare him a bit and there is a scene of the Commander eating all manner of Klingon food, including a bowl of worms. It's interesting that not only are these guys the bad boys of the universe, but they eat absolutely nothing conventional (as far as the crew goes). Because they are disgusting, their food must be also. Anyway, Riker must face off against the aggressive, dangerous Klingons to gain status on the ship. Because of his rank in Starfleet, he assumes his same role on board the new ship. There is trouble, of course, because these warlike characters see him as trying to subvert their ship. They will not listen to reason and Riker must act. These Klingon episode always make me wonder how they managed to do rudimentary things on a day to day basis if they spend so much time killing an maiming each other. This "dying with honor" thing still involves dying, a seemingly counterproductive activity. The episode does a good job of showing us the ship, and Riker is a worthy match for its crew.
