A group of young people takes a pleasure boat trip to Abkhazia. Suddenly, they find themselves trapped on a marine farm infested with man-eating sharks. In order to escape, they will need not only to join forces, but also to risk their lives for the sake of others.
After a fire on an abandoned farm near a small provincial town, several female bodies are found buried. All the women have been killed in the past two years, their hands are tied behind their backs with fishing line and their mouths are filled with sand. One of the victims is the wife of a local influential businessman, Eduard Kalashnikov, who disappeared five years ago. His daughter Alina, who came to see her father and introduce him to her fiancé Denis, gets entangled in a web of fears and suspicions. For the first time in her life, Alina herself makes a serious decision: she remains in the city and tries to figure out what is happening, despite the danger, risking her life and love. She will have to grow up, understand how cruel this world is, and make a choice between the two most dear people.
