On board the U.S.S. Kharon, twenty year old Summer works with her father while secretly planning her own future. Her plans take a turn when she discovers a plot against her family. The ship's doctor, Jung Rudolph, has been waiting for the moment when he could strike and steal her father’s medical journals.
