WW 2: A German special unit tries to thwart British ambitions to block a narrow water gap in the Danube River in order to cut off the German supply line. Then the unit is tasked to land behind the Russian lines to guard a strategic bridge.

The famous-notorious Division Brandenburg was (in wartime) under command of Admiral Canaris. But, the death brave division, joined by men, who where not really quite volunteering, received a command: Sulina, a harbour at black sea, where urgently needed oil is turner over, should be prevented from an attack. The plan is worked out and some more men need to volunteer, to let it become real. A war-, but also a contemporary history movie (1960).
