The film takes place in a summer youth camp by the sea. Tonya, a quiet, reserved and trusting girl, becomes the neighbor of Lyudka, a bright, strong and calculating girl. They fall in love with the same boy. It seems that timid Tonya has no chance against sexy Lyudka, but suddenly it turns out that Tonya has supernatural abilities that she cannot control. An unsociable, hunted teenager who does not understand the nature of his terrible power. Those around her consider her a real witch, not suspecting that in fact she is not a witch. For some, these holidays will be their last, and those who can survive will never be the same again.
