The Enterprise assists a race who have lost one of their shuttles. This race has no gender but a few of them do prefer a gender and try to act like that gender which is considered perverse. The scientist/pilot who assists Commander Riker is one of these and they fall in love. The shuttle turns out to be hidden inside a pocket of Null Space which the Enterprise charts and then attempts a rescue. The rescue is succesful but the scientist/pilot's secret is discovered and she/it is taken away. Riker attempt a rescue but is too late as she/it has already undergone pshycotectic therapy to "cure" her/it.
