Yesterday they were students, today they're fighting for their lives.

Lendorf School of the Youth was founded by a World War II veteran for troubled teens, but fast forward to present day, as nuclear bombs take the world, they are evacuated to a bunker. Rubble on the surface leaves them unable to open the door and without contact to anyone outside, they are trapped with less than a year's worth of supplies.

Students who had already been outcasted as troubled are now left in a world without law. As deadly choices are made, alliances are picked, and rebellions rise, friends will divide and enemies will align.

A girl with a false name.

A delinquent with a knack for locks.

An athlete who seeks revenge.

A descendant from the Lendorf bloodline.

They will have to move on from their past and create a society if they are to survive. At the end of the world, rules and order will change, but one thing remains the same-don't trust anyone.
