Former star infantry sergeant, huntsman Andrei Skvortsov becomes a guide for millionaire Edmond Marvell, who arrived with his daughter Remina on the distant planet Siren. Marvell wants to get his hands on the richest mines of the planet, and at the same time show his pampered daughter the other side of life. Skvortsov is not averse to earning extra money, and Marvell gives him a very strange task: to arrange a fake escape for Remina into a mysterious jungle full of nightmarish monsters. Neither the millionaire nor the huntsman suspect that the girl is being hunted by the interstellar brotherhood of the Simmons - space bandits who have their own designs on Siren's treasure.
