Syfy has set the UK premiere date for Siren, the gripping mermaid-themed thriller originally produced by Freeform in the United States. The series is set to debut later this April, bringing a dark reimagining of folklore to British audiences.

Siren is set in the coastal town of Bristol Cove, a place steeped in mermaid legends. When a mysterious young woman named Ryn appears and begins to wreak havoc, the town is forced to reckon with the reality of the myth they’ve long embraced.

The show stars Eline Powell as Ryn, whose performance brings an eerie blend of innocence and danger to the role. Alex Roe and Fola Evans-Akingbola round out the central cast, portraying marine biologists drawn into the escalating conflict.

Unlike traditional fantasy dramas, Siren explores environmental issues, scientific curiosity, and ethical dilemmas while still delivering suspenseful storytelling. The darker tone and unique premise distinguish it from more whimsical mermaid tales.

Syfy’s decision to air Siren reinforces its interest in showcasing genre series with fresh twists. The show is expected to appeal to fans of supernatural thrillers who are looking for something a little more haunting and mysterious.
