It's 1979 and Laurie Caswell is working as a bookstore clerk at the Northbrook Mall. That Saturday evening, she sees a movie with her boyfriend, Dennis Nolan. Instead of dining at a restaurant, the teenage couple goes to her parents' suburban house for some adult beverages. He leaves, and in the early hours of the morning, she has a horrifying nightmare.

A nightmare of a future where the mall resembles a prison. It's populated with overweight, black-clad people wearing face masks, and lining up outside the former Sears department store for mandatory Convict-21 injections.

Will the nightmare come true, or will the old book she discovers the next day at a yard sale help change the course of humanity forever?
