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 abizarre 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.
