"The Ensigns of Command" makes a move on the gang (who are joined by guest host, Liz Hardee), and they are torn on whether it's a welcome one or not. Ten Forward hosts a karaoke night, Geordie finds his limits, and Data channels Larry the Cable Guy. Meanwhile, Marcy seduces Data, Liz becomes a fashionista, Cameron survives an assassination attempt, and Rob takes over the show. Engage!
