They’re trapped inside a prison when the power goes out…

Molly is determined to get the troubled teens she teaches back on the right path and is convinced a trip to a local prison will show them the consequences of bad behavior. But when an EMP blast knocks out all power across the country, Molly and her five students, along with their former-Marine bus driver, Colton, are locked in with the prisoners with no safe exit.

The guards are little help against clever convicts, and when a riot throws everything into chaos, Molly and Colton must find a way to get to freedom with their charges, even if it means trusting a prisoner who is using them for his own gains.

Prisoners aren’t the only danger in the suddenly powerless world. Escaping the prison may be more dangerous than staying inside as it becomes clear to everyone that the power isn’t coming back, and society is about to crumble.
