Florence, 1969.
Dianora, the eldest of the three Coletti sisters, announces to her younger sisters, Betta and Gingi, that she is going to marry Giorgio in June. Giorgio is a star athlete with Assi Giglio Rosso, handsome, intelligent and… violent.
His real plan, however, is to get his hands on the Coletti family pharmacy. He has recently become the coach of a group of mediocre athletes and is trying to help them win competitions using amphetamines, which have just been banned from the Olympic Games.
Not only does he beat Dianora, he also tries to produce illegal drugs in her family’s pharmacy, risking the good reputation the business has built in the city if the truth comes out.
Betta and Gingi therefore do everything they can to drive him away from their older sister. But after saying “yes”, Dianora cannot simply leave him, because divorce does not yet exist in Italy.
So the two sisters decide to try to… eliminate him, killing him with his own weapon: amphetamines.
Will they manage to commit the perfect murder and save themselves, the pharmacy and, above all, their sister?
