Dead Swallows (2018)

Sasha, a singer at a musical theatre, persuades his friend Kulik to take him to a remote sacred place for fishing. Soon they find out that wood spirits live here. Kulik warns Sasha to ask them of nothing and not to fool the evil spirit, but he breaks the taboo — and now the spirits demand blood payment. Kulik faces a difficult choice: to leave Sasha in the forest and escape, or pull him out and pay with his life.
