Aboard the U.S.S. Enterprise as an officer alongside Spock and Captain James T. Kirk, Fallon Kirk discovers new things about her life and her own destiny that she never knew before. The crew are like her family, since her mother was nowhere to be found and her father was always out on differing voyages. So when an inside job is weeded down to five crew members, it's difficult for Fallon to digest. However, someone on board hurts Spock, and this anger makes her unafraid to hurt anyone else who stands in her way of justice. But…where did that anger come from? He would be alright, so there was no need to worry or be afraid. Yet all of this is strong in her. She feels a compulsion to kill whatever hurt her family. Only…what if the enemy was her family?
