A producer convinces some young creators of horror props to set up a 'haunted house' and use it as a film set. The building is an old haunted film studio: 30 years earlier an actor in a clown costume went mad and killed himself and his lover in a fire. But by communicating with the ghosts, the kids discover that the real story of what happened is quite different... A passionate, vintage-styled homage to the Hong Kong horror comedies of yesteryear.
