Mykel Hawke is a former Special Forces survival expert. His wife Ruth is a television journalist. Together, they take on some of the most forbidding and remote locations around the world. Dropped into each spot, they must survive as a team for four days and nights, with only a knife and the clothes on their backs. As they test their will and their marriage, the two find common ground standing up to nature as husband and wife in the wildest places on Earth.
