This shopping trip is endless.

During a quick trip to his local shopping mall to get his phone fixed, Luke Chesterfield is thrust into chaos when a nuclear bomb is detonated over his hometown.

Thanks to Cold War era defenses, Luke and a handful of shoppers survive the ordeal but are trapped inside the mall, isolated with only the resources available within the various retailers to navigate their new existence. Jack Jay, a handsome and confident electronics store technician, catches Luke's eye, but their budding attraction is put on hold when Luke unearths a conspiracy among the mall's higher-ups to pick off those who remain trapped inside.

Luke, Jack, and a ragtag team of other survivors, including a department store cashier with a proclivity for weaponry, band together to uncover the secrets and eliminate the threat. But the clock is ticking...and not everyone in their newfound group of friends will survive.
