A priest, a rock star, and a demon walk into a shopping mall...and then the apocalypse begins.

Christmas Eve, 1985.

Shoppers flood the aisles of Mallzilla, Springfield's largest shopping mall. But when Abaddon, one of the Devil's deadliest soldiers, is unleashed, the mall becomes the epicenter of a battle between good and evil.

As Abaddon recruits an army of possessed mall-goers, a group of unlikely heroes, led by Father Sam, the mall's resident priest, must band together to stop him. As the body count rises and the stakes get higher, the mall becomes the last line of defense against Abaddon's quest for world domination.

Can the Mall Priest and his team send Abaddon back to Hell, or will he succeed in building an army of darkness?
