High in the Andes Mountains on the legendary Inca Trail, four thirty-something professional women embark on an Ivy League hike to help them confront their online dating dependency, only to find themselves victims of a predators ruse, and soon in a fight for their very lives. The women are eager to leave relationships behind for a while, but their intent to cast off their search for a soul mate falls by the wayside when handsome, magnetic Rodrigo, their hike leader, proves too mesmerising to resist. Friend is pitted against friend as the women vie for Rodrigos attentions. Rodrigo manipulates them into participating in a heinous ancient sacrifice that will guarantee the success of his megalomaniacal dreams. But unbeknownst to the hikers, they have been under the vigilant presence of Taki and Koyam, two elderly indigenous women who understand the danger the women are facing at the hands of Rodrigo.
