Freeform's "Siren", previously titled "The Deep", is a fantasy drama series set in the coastal town of Bristol Cove, which legends tell was once inhabited by mermaids. The town is turned upside down when a mysterious girl (Eline Powell) appears and begins wreaking havoc upon the small fishing town.
Created by Emily Whitesell ("Finding Carter"), the show also stars Alex Roe, Fola Evans-Akingbola, Ian Verdun, Rena Owen, Sibongile Mlambo and Chad Rook.
"Siren" premieres tonight, March 29, 2018, on Freeform at 8p.
