Into the nebula

A strange nebular dust attracts the Enterprise, and the crew discovers a dying planet, Krantin. A series of explosions and a vanishing ship cause the crew to believe another group is causing the death on the planet. The leader of Krantin's society does not trust the Enterprise crew--after all, they are an alien force to him--and has the away team arrested. Data must find a way to save his crewmates or watch two worlds be destroyed!--Résumé de l'éditeur.
