The Ruins follows two American couples enjoying a pleasant, lazy beach holiday together in Mexico. On an impulse, they go off with newfound friends in search of one of their group--the young German, who, in pursuit of a girl, has headed for the remote Mayan ruins, site of a fabled archeological dig. This is what happens from the moment the searchers--moving into the wild interior--begin to suspect that there is an insidious, horrific "other" among them.
