The world may be recovering from a global zombie outbreak, but that's not stopping Dean from getting married. His friends have organized the ultimate stag weekend. In the aftermath of the pandemic, private companies are creating money spinning ways of disposing of the undead. The stag party, along with a PVC-clad stripper they've hired, go to play Zomball; like paintball, except that you get to shoot zombies. What begins as adrenaline fueled entertainment, soon turns into a game of life and death, when the stags break the golden rule and the zombies attack. Suddenly, the mother-in-law is the least of Dean's problems, as he and his friends fight for survival in this gory and hilarious zom-com.
