For as long as they can remember, Victor and Genevieve have been told there is one room in their grandmother's house that is absolutely off-limits. Nobody will say what's inside... just that the door is never to be opened. This only makes Victor more curious. So when he and his sister are alone in the house, he takes his chance. Inside, they find a vast collection of clown dolls, each sinister in its own way. Once the door is open, the clowns will not be contained. They break out into the world... and that's no laughing matter. Can they be stopped?
