A strange nobleman returning after years abroad to a small Bohemian village in the beginning of 19th century. The nobleman feels closer to animals despite looking like a human. He is a Hastrman - a water spirit. Water is his element. He loves it, understands it and communicates with it. He needs water not only to sustain his life, but also to gain superhuman strength and dexterity. In this romantic, fantastical, yet ironic story, love brings Hastrman unexpected happiness with an agonizing dilemma: whether to remain a wild creature or to cross the boundaries and get closer to become a human. Vivid and earthy folklore of local villagers brings authenticity to pagan folkways, yet the story ends in present times.
