In season six of Star Trek: The Next Generation, the dangers grow even more dire for the crew of the Enterprise. During a behind-the-lines mission, Captain Jean-Luc Picard (Patrick Stewart) falls into the hands of a seasoned Cardassian torturer. In an attempt to learn the truth about his father, Worf (Michael Dorn) breaks into a Romulan prison compound. James Doohan returns when a transporter malfunction resurrects the original series' Chief Engineer Montgomery Scott. Riker (Jonathan Frakes) copes with a bizarre identity crisis that pits him quite literally against himself. And Data's (Brent Spiner) quest to understand emotion introduces him to the concept of rage.
