SYRENA(Astrid Berges-Frisbey)A beautiful, enigmatic mermaid who swims against the tide of her more lethally-minded sisters of the sea. Mystery surrounds the mermaid Syrena, even down to her true name, for "Syrena" is only what she's called by missionary Philip Swift during her captivity by Blackbeard. After her fellow mermaids attack Blackbeard�s crew at Whitecap Bay, Syrena and Philip begin to recognize a quality in each other that draws them together, allowing them to become allies against a common enemy in Blackbeard. Each discover more of their true beings, but risk their lives when they listen to the sounds of their hearts. PHILIP SWIFT(Sam Claflin) Idealistic, courageous and fearless, this missionary defies even Blackbeard in an attempt to rescue the terrible pirate's soul. Philip Swift is on a mission completely unlike the pirates, scalawags, kings and sailors all in pursuit of the Fountain of Youth. His is a mission of salvation, and even when taken prisoner by Blackbeard and ruthlessly tortured, Philip's spirit remains unbroken. But something stirs inside of his heart as well as his soul when he encounters the mermaid he calls Syrena on the quest for the Fountain of Youth-feelings which prove that the path to real deliverance may lie beyond the Good Book he carries with him.
