1945. Germany is defeated, all submarines ordered to return to ports. But to return is to surrender and be captured. You command one of the u-boot VIIc type boats and decide to sail to the shores of neutral countries to save your boat and crew. But on the way you are trapped by many dangers-minefields, magnetic mines, signal buoys, boats with depth charges, patrolling convoys and other dangers. But freedom is not given to simple price.

Peculiar properties:

stressful, and at the same time relaxing melancholic soundtrack
