Both Les and his son have gone through their fair share of drama, Les suffering through three broken ribs, a punctured lung, torn chest muscles and a dislocated shoulder. These injuries were a result of he and his crew's horrific car accident while caravanning down a road in Mongolia while they were there filming Survivorman. Logan was diagnosed with leukemia at 16 and spent six months in the hospital. Fortunately, he made a full recovery. Now this father and son team put themselves to the ultimate test of both their wilderness skill sets and their relationship as they explore what it takes to exist in the deserts of Mongolia, the remote coast of Tofino, the dense forest of Wabakimi and deep in the jungles of Ecuador.
