Finn, Madison, and Johnny all have the worst lives - Finn has a mental disorder, near vision loss, and no friends outside of the trio, Madison has an abusive father, and Johnny has 2 dead parents and no one who really cares for him. Outside of school, they just want to have fun, be normal, and have a great summer - that is, until a black force sucks them into various alternate dimensions, chock-full of fear and torture. Now, their only goal is to escape from the sinister places - alive.
