The girls make reservations at a private beach resort to continue their Sailor Warrior training. All they really want to do, however, is have some fun... that is, until they realize that they're booked their stay at the "Adam's Inn". Even though attendants at the Inn look like they're straight out of classic horror movies, the girls make the best of it. Ami tries to befriend Sakiko, the little girl who lives there, but her father rebuffs her. He hypnotizes Sakiko to invoke the powerful spirit inside of her. Unfortunately, the spirit goes out of control and starts attacking everyone.
