Plot Synopsis

The coastal town of Bristol Cove, known for its legend of once being home to mermaids, is turned upside down when a mysterious girl, Ryn, appears and begins wreaking havoc upon the quaint village. Using their resources, marine biologists Ben and Maddie must work together to find out who and what drove this mermaid out of her home, and discovery if there are more like her out there. Soon after the girl's arrival, Ben and crew of The North Star uncover a device emitting a strange sound. Meanwhile, Ryn finds shelter in the home of the local folklore expert. Then, Dale and the local police's investigation starts pointing directly to Ryn, meanwhile Xander and Calvin's search for Chris heats up when they locate the nurse who works at the military bunker.
