A group of artists consisting of young actors Wilfried and Matthew, as well as actresses Sophie, Mathilde, and mute Jenny, were hired by millionaire Axel de Fresen to perform Little Red Riding Hood in his isolated castle to celebrate his grandson's birthday. At the same time, the police stated that a serial killer was raping and killing young women in the nearby forests in the area. At night, this group of people felt trapped and threatened in the castle, guessing who the murderer was and where he was.
