Greg Heffley is under a lot of stress right now. His mother believes that video games are turning his brain to mush, and she wants him to put the controller down and develop his artistic side instead. When Greg comes across a bag of gummy worms, though, he gets an idea. Will he be able to get his mother off his back by filming a movie... and will he become wealthy and famous as a result? Or would doubling down on this strategy only make Greg's problems worse?
