Siren

Down 

Here is the Official song called "Down" by Of Th3 D33p (also known as Aryeh-Or (who plays Mate) from the Season Finale of Season 3 of the FreeForm series: Siren, featuring Alix West Lefler as Ryn's daughter Hope. “Siren” takes us inside Bristol Cove—a coastal town known for its legend of once being home to mermaids. 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 Alex Roe as Ben Pownall, a bright marine biologist who finds himself drawn to a mysterious new girl in town, Ryn Fisher, played by Eline Powell who is a strange young woman with a deep dark secret: she is a mermaid. Fola Evans-Akingbola as Maddie Bishop, who is also a marine biologist who works with Ben, and is highly suspicious of Ryn. Ian Verdun as Xander McClure, a deep sea fisherman on a quest to uncover the truth; and Rena Owen as Helen Hawkins, the town eccentric who seems to know more about the mermaids than she lets on. Based on a story "The Deep" by Eric Wald and Dean White who both serve as executive produces. Emily Whitesell is on board as Showrunner and Executive Producer. Brad Luff, Nate Hopper and RD Robb are also attached as executive producers. This song is used in the scene, where Ben rescues Hope from her kidnappers.
