Counselor Troi is held captive on a deserted planet by a slick, black, oily, sentient and immortal puddle of evil.
When the Enterprise answers a distress call from a downed shuttlecraft that was carrying Deanna Troi and another crew member the away team finds itself on a barren planet inhabited a creature made of primordial ooze named /armus. It has an intelligence that is directed at sadism and cruelty.
Unfortunately they lose one of the cast regulars as the creature kills Denise Crosby. Patrick Stewart engages in quite the battle of wits with it until they figure out how and when to beam up their crew. When is most important here as you'll discover.
A nice memorial service for Tasha Yar concludes the episode.
