Out on her first real archaeological expedition, Vivian Anderly gets herself in over her head after she gets separated from her team and ends up hopelessly lost in the wilderness.
As night descends and the temperature drops, her only hope is to find someone - anyone - to help her. While searching for her camp, she instead comes across a cave inhabited by a group of curious, handsome men dressed in primitive clothing, armed with weapons and tools that look eerily like the ancient artifacts that Vivian has spent her career studying.
Alone with them in the wilderness, will she be able to resist the pull of nature that draws her to these lustful strangers, or will she give in to her primal instincts and let nature run its course?
