In the idyllic and pristine suburban utopia of Heaven, everything remains perfect as long as the residents adhere to a single rule: avoid any interaction with “The Evil One” residing beyond the massive wall encircling the community.

There, the child encounters the Evil One, who tries to impart the forbidden knowledge that has been kept secret from everyone.
