Gaia

Temporarily assigned to assist the Federation's Department of Temporal Investigations, the crew of the Starship Enterprise return to the planet Gaia in the Gamma Quadrant to investigate the remains of a colony lost to time. Upon arrival, however, the crew are shocked to find a Defiant Class starship stuck within the quantum energy barrier surrounding the planet. A lifeboat holding the last survivors of a civilization lost to time, the Enterprise crew must decide whether saving the survivors is worth the risk it will cause to the timeline.
