Freeform has released the Official Synopsis of Siren episode “All In” (2.10) that will be aired on Thursday, June 20 at 08:00-09:00 PM.
With Elaine Pownall’s health worsening, she seeks treatment from the military’s medical trial using mermaid cells, but the procedure doesn’t come without side effects to the mermaids. Meanwhile, Helen and Rick learn more about the hybrid status, their history in Bristol Cove, and discover they are far less alone than Helen once believed.
The series stars Eline Powell as Ryn, Alex Roe as Ben Pownall, Fola Evans-Akingbola as Maddie Bishop, Ian Verdun as Xander McClure, Rena Owen as Helen Hubbell and Sibo Mlambo as Donna.
In Siren, the coastal town of Bristol Cove, known for its legend of once being home to mermaids, is turned upside down when a mysterious girl (Eline Powell) appears and begins wreaking havoc upon the quaint village.
“Siren” is based on a story by Eric Wald and Dean White who both serve as executive producers. Emily Whitesell (“Finding Carter”) is on board as showrunner and executive producer. Brad Luff, Nate Hopper and RD Robb are also attached as executive producers.
