It has been two years since the last time that the senshi and their knights have been called upon to defend the earth from invaders.  Life goes on as it often seems to until the senshi reach their graduation and recieve an invitation by a mysterous benefactor to an exclusive luxury spa in the mountains deep in Japan.  Each senshi finds herself and her knight picked up by a limousine which whisks them away to the resort.  Somewhere during the trip, they doze off, only to awaken standing in the resort.  It's the perfect vacation and the perfect trap.
