A young filmmaker obtains a mysterious device that unleashes the full force of cinema on his front lawn. “Plot Device,” a nine minute short film directed by Seth Worley, demonstrates first hand that today budget is no longer a constraint when you truly wish to create an immersive film experience.

However, the selling part is so subdued that you don’t really mind the little trickery the film plays on you.
