Freeform’s The Deep has a new title – Siren – and a season one order of 10 episodes. Freeform released the first teaser trailer for the drama while announcing the series is moving forward with Alex Roe (The 5th Wave) and Eline Powell (Game of Thrones) in starring roles. According to the network, Siren will air during the 2018 summer season.

Siren is based on a story by Eric Wald and Dean White and has Finding Carter‘s Emily Whitesell on board as the showrunner. Wald, White, and Whitesell are executive producing along with Brad Luff, Nate Hopper and RD Robb.

The Plot: 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, a bright marine biologist who finds himself drawn to Ryn, a mysterious new girl in town played by Eline Powell, who is a strange young woman with a deep dark secret.

Fola Evans-Akingbola (An American Exorcism) stars as Maddie, also a marine biologist who works with Ben, and is highly suspicious of Ryn. Ian Verdun (Life’s a Drag) stars as Xander, a deep sea fisherman on a quest to uncover the truth; and Rena Owen (Star Wars Episodes II and III) as Helen, the town eccentric who seems to know more about the mermaids than she lets on.
