One year after the events of 'Lost', Rex continues to search for a way back into the backrooms, and search for a way back to Kierstan. But as he begins to fail again and again, he asks himself if he even should be doing this. After all, it was so rare to escape from the backrooms the first time, let alone a second. What if this time he doesn't make it out? What if he fails to help Kierstan? When an opening to the backrooms finally reveals itself, Rex must make a choice. Relish in a life that he knows he chose, blissfully living with the knowledge he left her behind. Or sacrifice it all for a second chance. A second chance for them both to be free from the backrooms. And when he makes his choice, his sister Stacey and Kierstan's father Ted will have to face the repercussions of either outcome. No matter what Rex does, there will be severe consequences, and everything will be on the line.

Rex wakes up in a familiar, but strangely different world than his own. He has no memory of arriving in this place, and has the incessant feeling he must escape, or he'll be trapped in this unsettling world forever. Combined with the blood found on the ceiling in the spot where he woke up, the strange creatures that stalk him anywhere he goes, and the new girl he's met with extensive knowledge on where they are and what the creatures are, Rex knows that this place is unlike anywhere he has ever been before, and he must traverse it to escape it - which may be the death of him.
