In the early morning of April 9th, 1940, the Danish army is alerted. The Germans have crossed the border; Denmark is at war against Europe's strongest army. At the Southern border, the Danish homeguard are ordered out to hold back the forces until the Danish reinforcements can be mobilized. In the fatal hours, we follow second lieutenant Sand (Pilou Asbæk- Lucy, A Hijacking) and his small and inexperienced band as the first Danish soldiers meet the enemy in combat on that fateful day… April 9th, 1940.
