Full of chills and twists, a twelve-year-old boy is thrilled that he'll get to play endless games at his family’s arcade, but soon realizes he’s in the fight of his life when he’s forced to save himself and his possessed Uncle from a sinister video game.

Danny is spending a week with his Uncle Bill who runs a massive retro arcade called PixelWorks. His only plan is to play as many games as possible from open to close, but he wasn’t expecting to find the Holy Grail of arcade collectors, a gruesome looking game titled Grin.

Anyone who plays the game becomes surprisingly violent, and soon with the help of his friend Jodi and a knowledgeable videogame streamer, Danny realizes that Grin holds the soul of a dead serial killer.

Soon, the killer makes the jump into Bill’s body, and it’s up to Danny to figure out a way to stop him for good.
