Army of the Dead (2008)

Plot

In 1590, Coronado led a thousand soldiers on a quest for the mythical city of El Dorado, but they vanished without a trace. Centuries later, a university professor and his students explore caves in the Baja peninsula, unknowingly awakening a dormant curse. They quickly find themselves embroiled in a fierce struggle for survival against skeletal warriors—the undead remnants of Coronado's ill-fated expedition. As the ancient curse unfolds, the group must confront not only the terrifying soldiers but also the dark legacy of ambition that led to their demise.
