The day after a young man graduates from high school, he attempts to cross the street. As he makes his fateful crossing an absentminded driver speeding down the very street he is crossing fails to notice him and is about to hit him with her car when the man is mysteriously abducted by a supernatural force. Before he can fully realize what was about to happen, he finds himself in a dreadful place: the eerie yellow-carpeted halls of the first level of The Backrooms.

Fortunately for him, whatever supernatural force saved his life does not merely abandon him to the relentless cruelty of The Backrooms. The process of shunting him across dimensions has transformed into something both more and less than a human… A Jumper. Driven forward by his will, and empowered by his F L E S H after realizing that he has recovered from the physical disabilities that plagued him his entire life, he cautiously steps into The Backrooms, believing that he has no choice but to stare down the dangers of The Backrooms and overcome them.
