The Hatfields & McCoys of outer space
After a Federation oupost is raided, the Enterprise heads to Acamar Three (it would seem that most planets in Star Trek need to have numbers connected to them) where they meet Marouk (Nancy Parsons), leader of the planet. Marouk explains that a group called "the Gatherers" is to blame for the raid on the outpost. After centuries of blood feuds, the renegade group of Acamarians who call themselves "gatherers" live as space-faring nomads, "gathering" the belongings of others.

Marouk has a sincere desire to reintegrate Acamar Three's lost sons. Marouk's servant, Yuta (Lisa Wilcox), is always at her side. She is almost like a Labrador retriever, being Marouk's "gofer" for everything and treated sometimes like a robot instead of a young woman. Riker finds her to be quite fetching and the two take a liking to each other.

Picard volunteers to help Marouk locate the clan leader of the Gatherers, Chorgan (Stephen Lee), so that they can make peace with them, give them amnesty for their "gathering" crimes and give them a piece of land so they can start to reintegrate into their society.

Unseen to everyone else, Yuta runs across an elderly Gatherer, a member of the Lornack clan, who recognizes her from years before. With a touch of her hand, the old man drops dead. Crusher finds that the man, despite his age, was relatively healthy, but died of a rare virus that was almost designed to attack him specifically. This is the second such death and a connection is made - members of the Lornack clan are dying and the only one left is Chorgan. But who could be killing off the Lornacks? Their sworn enemies were wiped out 50 years earlier?

Some sleuthing by Data and Crusher reveal the secret and Riker must beam into the middle of talks with Chorgan, Marouk & Picard to stop Yuta in her tracks.

An interesting tack on an old theme.

pretty good
This one is pretty good. As someone who has seen and is collecting them all, this is one of the first 40 that I have purchased. Out of 176 or so episodes, that should tell you something. The caracters are very believable and there isn't too much over acting. The story will hold you in for the entire episode.
