Synopsis:
Bruce Wayne is invited to Slade Manor, the home of Monica Slade for a murder mystery. Ten guests arrive and are given roles to play by Monica. When the lights go out, Monica becomes a real victim as she falls out a window to her death. Bruce leaves the party to become the Batman. He eventually uncovers Rene Cesar as the killer. Jake Sweeney who is Cesar's son is also involved, but Rene shoots him. Batman is thrown out the window, but rescued by Hamish Stewart, a giant who worked as assistant to the mansion's builder Deacon Slade.

The mansion begins to slide off a cliff after Rene sets off explosive charges. Stewart holds the supports long enough for Batman to get everyone else outside. Rene falls to his death through the open window.
