The Opportunities of Rosa (1981)

Rosa (Marina Suma) is a low-level worker who decides to quit a nowhere job and turn to prostitution instead, all the while living with a boyfriend who is dealing drugs for his financial support. Entering into the picture is a homosexual friend who wants a child of his own and is willing to donate a good apartment to the couple if Rosa will marry her boyfriend and bear a child. She does get pregnant, but by that time has had it with the constant presence of the homosexual, and is having second thoughts about her pregnancy.
