In May 1941, Major General Golovko, commander of the Soviet Northern Fleet in the Murmansk region of the Soviet Arctic, foresaw the imminent outbreak of war and ordered the training of future special operations personnel for enemy rear operations at naval bases. Civilian female Martha was also invited to the base for training due to her excellent shooting skills. On June 22nd, the Patriotic War broke out, and the German army built a shore artillery position on the Norwegian coast, seriously threatening the safety of Soviet ships and Allied Soviet aid fleets entering and exiting the port of Murmansk. The Golovko pirates ordered the assault team to destroy the German shore artillery position and control it in the hands of the Soviet army. Martha and the assault team embarked on the journey.
