The Galactic Whirlpool

On a routine mission in deep space, Captain James Kirk and the crew of the Enterprise discover a lost city, drifting in space, more than 20 years from the nearest Human colony. Its inhabitants are human, but so isolated that they are unable to grasp the existence of other worlds besides their own. Outsiders must be demons. Earth is a place that exists only in legend, in the tales of their ancestors. But time is running out for this forgotten civilization... their world is being pulled straight towards the center of a galactic whirlpool, two orbiting black holes in space. Can Kirk convince them to trust him, before their world is destroyed forever?
