“She is extremely violent.”

There isn’t nearly enough entertainment centered on scary killer mermaids, which is why I’m personally interested in checking out Freeform’s upcoming “Siren,” a brand new horror-drama series that will have its 2-hour premiere on March 29.

In the series, predatory mermaids return to take back their ocean. Check out a new teaser trailer below, along with the series’ official key art at the bottom of this post.

“Siren” is set in Bristol Cove, 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 (“The 5th Wave”) as Ben, a bright marine biologist who finds himself drawn to a mysterious new girl in town, Ryn, played by Eline Powell (“Game of Thrones”), who is a strange young woman with a deep dark secret.

Fola Evans-Akingbola (“An American Exorcism”) also stars as Maddie, 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.

“Siren” is based on a story by Eric Wald and Dean White, who both serve as executive produces. Emily Whitesell (“Finding Carter”) is Showrunner and Executive Producer. Brad Luff, Nate Hopper and RD Robb are also executive producers.
