Horror remake starring Rufus Sewell. Angus (Sewell) and Lily (Carla Gugino) are travelling the Irish countryside with their carnival sideshow when they befriend a wealthy old sailor. After giving him a ride to his castle, he shows them his deadly prize: a real, live mermaid held captive in a tank. Eager for fame and fortune, Angus and his crew steal the sea creature and make plans to set sail for America. After loading their cargo and boarding a boat, they soon learn that the animal they possess is as dangerous as it is beautiful. But nothing can prepare them for the horror that awaits them as their boat drifts further and further out to sea.
