Detective Joe Miller is handed a key that turns out to be rather important. Several obscure persons appear to be looking for this key. Miller discovers that the key fits a particular door of a room in a motel. But it turns out that this room is physically completely different from the rest of the world, in fact, it leads into a parallel universe. The room also offers space for some objects with magical powers, which are very popular with so-called 'object hunters'. When Miller's daughter is in danger, he must confide in these eccentric figures to find the right combination of objects.
