France, 1890. Inventor Louis Le Prince vanishes under mysterious circumstances right after he created a device that, five years later, the Lumière Brothers will call The Cinematographer. What if they had stolen Le Prince’s idea and wacked him afterwards? The mystery remains for more than a century, until Luigi Cozzi picks up a strange book called “The Roaming Universe” in the horror museum of his pal Dario Argento. The origin of this enigmatic book troubles him. This particular science-fiction novel would have materialized during a spiritual session in modern day Rome.

Not only does this film actually exist, but it raises a more intriguing question. Is our world the only one, or are there parallel universes ?
