Continuing their journey back to Darkwood, our two friends pass by Stormy Pass a mountain pass beaten by a cold wind and by snow and infested with wolves. Zagor and Chico cross it with difficulty and, having reached the nearby village, discover that a monstrous creature threatens the entire valley!
The being that torments the inhabitants of Stormy Pass is a lycanthrope, a man who, during the nights when there is a full moon, turns into a werewolf. And it can be anyone because, as an old popular belief assures, even a man with a pure heart can turn into a wolf when the aconite blooms or the new moon shines!
