After the suicide of his twin brother Pippo, Giovanni, an actor past his prime, returns to his provincial hometown in Emilia-Romagna. Giovanni's brother Agostino and his uncle try to convince the mother that the death of her son was not self-inflicted but accidental. To the family's consternation, Pippo's former lover Wanda, a South American immigrant who lives in an apartment which he paid for her, shows no sign of grief. Giovanni learns that Pippo lamented that Wanda didn't love him and that she regularly meets with a young doctor. Although he blames her for his brother's death, Giovanni starts an affair with her.
Like many of Bellocchio's films, The Eyes, the Mouth contains autobiographical parallels to the director's life, here the death of his twin brother who committed suicide in 1968.[3]
