Between the first and second World Wars, we portray glorified and renown naval sea officer Felix Graf von Lucker and his fictitious ship Niobe, which is the 1887 built Amphitrite from Southampton. Von Luckner is famous for his tactical genius in the first World War, especially sinking 14 enemy ships and only losing one crewman, whilst always seeking a peaceful outcome - making him the ideal seaman.

During World War II, a young German soldier named Feldwebel Schmid is torn between his duty to the Nazi regime and his own conscience. As he witnesses the brutalities committed by his fellow soldiers, Schmid must decide whether to blindly follow orders or take a stand against the atrocities. Through an internal struggle, he comes to question the ideologies he once believed in and the price of loyalty in the face of inhumanity.
