Plot

In a brief prologue, a woman crouches alone in darkness, and screams for help before she is dragged by an unseen force. Two young American couples — Jeff, Amy, Eric, and Stacy go on vacation to Mexico. They meet Mathias, a German tourist, who is looking for his brother Heinrich. His last known location is an archaeological dig at a remote Mayan ruin in the jungle. They are also joined by Dimitri, Mathias' friend. The group reaches the ruins of a Mayan temple, and are confronted by Mayan villagers armed with knives, bows, arrows, and a gun. Mathias tries to explain their purpose, but the villagers do not understand Spanish or English. When Amy accidentally steps on some vines, the villagers become extremely agitated. Dimitri approaches the villagers, hoping to appease them, but they shoot and kill him. The rest of the group flees up the steps of the ruins.
