Three bumbling Army reservists, Larry, Bill, and Everett, find themselves eagerly anticipating a weekend of military drill, only to discover that their routine training is about to take an unexpected turn. Known more for their mishaps than their military skills, the trio dreams of real action, craving something more than their mundane civilian lives offer. Their wish inadvertently comes true when they mistakenly get deployed to Iraq, but due to an unforeseen series of blunders during their flight, they land far from their intended destination.

Upon arrival, the group believes they have arrived in Iraq, but in reality, they've been dropped in a remote Mexican village. Mistaking the desert landscape of Mexico for the Middle East, they embark on a misguided mission to liberate the village from what they perceive to be insurgent forces. Unaware of their colossal error, they approach their mission with the utmost seriousness, employing their limited military training to organize the villagers and prepare for an inevitable confrontation. Their earnest, but clueless efforts to protect and serve, create a series of comic adventures as they try to navigate their way through a situation they are wholly unprepared for.
