Simon is the last heir of a Jewish banking family. His uncle promised him his fortune on the condition that he gets married and a son is born from this union. But Simon is gay and doesn't care about outdated Jewish traditions.

Klezmer musician Simon Eskanazy wrestles with his gay nature. His conservative, orthodox family, Parisian bankers, expects him to carry on the family name by marriage. However he's irresistibly drawn to attractive young men, from gay sauna visitors to, surprisingly, the hunky son of devout New York uncle Salomon. Still, Simon secures his considerable inheritance by wedding Rosalie Baumann, that ideal lover's sister, a grand family affair. This 'investment' will only pay off if it produces another generation, but the marriage goes sour.—KGF Vissers
