Introduction
Called to a remote colony by a distress signal, the crew of the Enterprise finds a deserted planet and an orbiting Klingon battle cruiser. As they put themselves at odds with each other, little do the two crews know that they are being manipulated into a false rage by a malevolent entity that feeds on emotions. Will they be able to put aside their differences in time to avoid being taken on a journey out of the galaxy, doomed to fight each other throughout an immortal eternity?
