This is another one of the solid, enjoyable and unremarkable episodes that populate much of the 3rd season. In this one, Riker is accused of murdering a scientist and lusting after his wife. Despite some similarities, each of the three testimonies diverges on enough key elements that Riker can't be immediately absolved.
Actually, what is weird to me is that despite being absolved of the murder, we never really figure out exactly what happened on that space station – and the show keeps going as if it doesn't really matter! Riker was effectively accused of attempted rape, and Counselor Troi herself suggests that the purported victim truly believes her version of events! Sounds pretty shady to me.
The best part of the episode lies in the testimony representing Dr. Apgar's view – all of a sudden, this wimpy scientist becomes a butt-kicking superhero – as I suppose he always imagined himself.
