Episode 3 - S1.E3

The students are dropped in the middle of the remote Scottish Highlands, where they learn survival skills required for life in the field. Training in the same mountains as 1940s agents, they are schooled in the same techniques which prepared a group of agents tasked with putting a stop to Hitler's atomic ambitions in Norway. In a freezing Scottish lake and on a sheer rock face, some of the students are forced to find previously-untapped reserves of mental and physical strength.
