During World War II, Renault, a German officer, was in agony because his fiancée was taken away by Nota, who was also an officer. Among the new batch of Jewish prisoners of war, Renault discovered Subu who looked exactly like his fiancée Alan.

Over time, Renault discovered that he had forgotten the flirtatious and unfaithful woman and fell in love with Subu instead. As time went by, Renault's attitude towards Nota also slowly changed from the initial dislike to mildness, but at this moment, a shocking fact emerged - Subu was Alan's biological brother; and Nota only robbed Alan because he deeply loved Renault, but because it was same-sex love and compatriot love, he never said it out...
