In Army of the Dead, Las Vegas is placed under quarantine after the zombie outbreak.
Zack Snyder’s 2021 film begins after an escaped military convoy causes an outbreak in Las Vegas. The United States government isolates the city behind a massive fortified wall, leaving the infected population trapped inside the quarantine zone.
The main plot begins when casino owner Bly Tanaka recruits Scott Ward and a team to enter the sealed city and recover money from a vault. Their mission must be completed before a planned nuclear strike destroys Las Vegas. The setting combines zombie horror with a heist structure.
Army of the Dead distinguishes between ordinary shambling undead and more organized Alpha zombies. This creates a hierarchy within the infected population and gives the film’s Las Vegas setting a broader mythology. The city itself is fictionalized for the story, but the recognizable casinos and skyline remain central visual elements.
