Leif Tronstad establishes contact with the War Ministry and a plan to destroy the Hydro facilities at Rjukan is drawn up. A small team code named ‘Grouse’ will parachute over Norway to prepare for British commandos who will arrive in gliders. Tronstad hand-picks Knut Haukelid as the leader of ‘Grouse’. Haukelid is a daring man with no respect for authority. But just before departure Haukelid ends up in a self-inflicted accidental shooting and Claus Helberg, an indefatigable worker hailing from Rjukan now heads the mission. Heisenberg travels to Copenhagen to meet his Danish mentor professor Niels Bohr – also a Nobel Prize winner. Bohr implores him to stop working at the bomb. Heisenberg fails to understand why. He dives back into his work on the bomb. In Rjukan, the new managing director Erik Henriksen is confronted with sabotage of the heavy water production. He fires an innocent employee as a warning to others. Operation ‘Freshman’ takes off with 34 British commando soldiers, but over the Norwegian mountains they fly into a snowstorm.
