When the arrival of a mysterious girl proves this folklore all too true, the battle between man and sea takes a very vicious turn as these predatory beings return to reclaim their right to the ocean.
The series stars Ben, a bright marine biologist who finds himself drawn to a mysterious new girl in town, Ryn, who is a strange young woman with a deep dark secret. Maddie, also a marine biologist who works with Ben, and is highly suspicious of Ryn.
It also includes Xander, a deep sea fisherman on a quest to uncover the truth; and Helen, the town eccentric who seems to know more about the mermaids than she lets on.
Thursdays on Freeform.
