Julian's friends attempt to cheer him up one night, but they only make things worse. His best friend Miles pulls a prank, hoping to make Julian laugh, but instead, he freaks out. He runs into the forest, getting lost, but when he wakes up in a windowless hallway with sticky brown carpet and peeling yellow wallpaper, it's clear he isn't anywhere he remembers. Running from monsters with sharp teeth and creatures that lurk in the dark, the unending maze appears to be a loop. To find the end, he has to venture across different rooms with puzzles and even sacrifice something that means the most to him. Is his life worth escaping, or should he accept his fate and become one of the monsters he is running from?
