In This Giant Papier Mache Boulder Is Actually Really Heavy, when three ordinary guys guys go to a sci-fi convention and start watching an old B grade movie they get a bit more when they bargain for. Suddenly they get sucked into the movie itself and are trapped in a low budget sci-fi universe.
At the helm of a rickety old spaceship they soon stumble into a trouble, make an enemy of the evil lord froth and rescue an uppity space princess.
To make matters worse one of them starts to think he is a sci-fi character. They embark on a quest to save their friend and get themselves home. Giant lizards, sexy amazons, kooky robots and enough crazy mayhem that could only be found in a B grade movie.
Will they survive long to solve it all and save the day?
