In a sun-drenched summer of change, two lifelong best friends, Claire and Hailey, face their final days together before a move threatens to separate them. Their wish for a miracle to stay together is answered in the most unexpected way when a fierce storm washes a magical mermaid named Aquamarine into their beach club’s swimming pool. Played with sparkling charm by Sara Paxton, Aquamarine is on a mission to prove to her skeptical father that true love exists, offering the girls a deal: if they help her win the heart of a handsome lifeguard Jake McDorman within three days, she will use her powers to grant their wish. As Emma Roberts and Jojo navigate the chaotic and hilarious challenges of hiding a mermaid on land while coaching her in the confusing ways of human romance, they discover more about friendship, courage, and the bonds that truly last. This delightful blend of comedy and heartfelt drama, directed by Elizabeth Allen, is a whimsical tale of summer magic where the greatest treasures are found not in the ocean, but in the connections we make.
