The Hungarian Forbidden Relations is a shockingly straightforward treatise on the subject of incest. A woman's (Lili Monori) love for her brother (Miklos B. Szekely) goes far beyond filial devotion. His feelings for her are likewise intense. The problem goes beyond conventional morality: incest is illegal in communist Hungary, and as a result both brother and sister are thrown into prison. American audiences weren't always certain whether Forbidden Relations was simply a paean to individual freedom or an advocacy of impure love.
