Mauvais Sang

Mauvais Sang (1986)
A sexually transmitted disease called STBO is sweeping the country; it's spread by having sex without emotional involvement, and most of its victims are teenagers who make love out of curiosity rather than commitment. While a serum that can treat the disease has been formulated, it's been locked away in an inaccessible government building. A woman hires two men to steal the serum.
