At a stopover, Madame Reza, a fortune-teller, tells Anna that a restless spirit is haunting her in her dreams, trying to send a message and return to life.
Suzy reveals that Jennifer has an imaginary friend named Danica, who is actually a child who drowned in the resort's swimming pool.
Upon recovering, Giselle warns Anna that the pool is inhabited by vengeful spirits, and reveals that she is also searching for her father.
Later that night, Jennifer is lured into the pool by Danica and pulled into the water by the creature before reemerging and casting an ominous glance at Anna.
Anna calls Madame Reza, who tells her that Jennifer was possessed by Danica in the pool and that her spirit is already in the afterlife.
She then realizes that Andrea was her playmate who was strangled and buried by Dave and Eddie underneath the pool's foundation after resisting their sexual advances fifteen years prior.
As Dave washes off evidence of Dennis' murder at the swimming pool, the creature emerges and reveals herself to be Andrea before pulling him into the water.
A year later, Andrea, in Anna's body, claims Alex as her boyfriend and celebrates Gusting's birthday as she sees her original reflection in a mirror.
