Selena, the daughter of the head of the vampire clan Victor, has been waging a war against werewolves alone for many hundreds of years. Of course, the vampires from her clan help her, but the girl always does the main work herself. In one of these battles, the werewolves answered the heroine with worthy resistance. Selena survived, but she lost a lot of blood. From the conversations of the dogs, she learns that the shaggy creatures have been looking for one man for a long time, in whose veins the blood of an ancient and powerful werewolf flows. The dog warriors believe that this guy will be able to end the war between the clans and destroy Victor. The girl also learns that David - her friend - is actually a traitor and enlisted the support of the Lycans to seize power over the vampire clan.
Nobody believes Selena and the only way to save the whole clan is to wake up Victor and tell him everything. So she does, but the plans are violated by werewolves who broke into the castle. Fleeing, the girl hurries in search of such a descendant of Lycans. It turns out to be a doctor named Michael. Now it depends only on him how this whole story will end. Its outcome will be directly related to the choice of Michael, who has already been turned into a beast. Whose side will he fight on?
