Agnieszka Smoczynska directs this Polish horror musical starring Marta Mazurek and Michalina Olszanska. Carnivorous mermaid sisters Srebrna (Mazurek) and Zlota (Olszanska) come ashore one night in Warsaw where they meet a family of musicians who, transfixed by their siren-like song, invite them to sing with them at a local nightclub. Becoming an instant hit with the clubgoers, their new life looks set to give them a fresh start but when Srebrna falls in love with a human Zlota worries that her sisters feelings will jeopardise their long term plan.
