This genre-defying horror-musical mash-up follows a pair of carnivorous mermaid sisters drawn ashore to explore life on land in an alternate 1980s Poland. Director Agnieszka Smoczynksa gives fierce teeth to her viscerally sensual, darkly feminist twist on Hans Christian Andersen’s “The Little Mermaid.”

This is the fourth part of our screening series Eastern Bloc Block, celebrating artists from Ukraine and former Soviet states.
