Three "Larians" are visiting the Enterprise on a diplomatic mission. Each has an interesting being about him. One is gregarious, attracted to Troi and food. He gorges himself and acts as a glutton for pleasure. The second is a hostile, confrontational bully, who chooses Worf to attend to him and then abuses his powers (obviously, Worf can do nothing because these are their guests). The third goes on a mission with Picard on a shuttlecraft. He barely speaks to Picard, seeming to be quite annoyed at being with him. A malfunction in the shuttlecraft sends them to a planet that has intense storms. They are trapped and Picard, leaving his "friend" behind (he was badly injured in the crash) tries a bit of reconnaissance but is hit by a bolt from the sky. He is rescued by an attractive young woman who takes him with her to her hiding place. She nurses him, but keeps him locked up. I think that if there is a bit of a weakness in the verisimilitude in this series, it has to do with shape changing and out and out magical abilities of the aliens. I will not spoil anything, but even in science fiction, there are some things that are far fetched. It's a fun episode if one doesn't think too much.
