The planet also hold a wealth of undiscovered archaeological treasures, which the Enterprise™ and its crew are dispatched to help uncover.Sent to the surface to assist an archaeological team, Geordi, Data, and Worf soon find themselves cut off from the Enterprise -- and the prime suspects in a series of terrorist attacks. The three Enterprise crewmen are imprisoned, relations between the K'vin and the Federation begin to crumble, and Kirlos' ancient underground machinery awakens from a centuries long dormancy, primed to release the most powerful destructive force ever known.
