Italy, 1977. Professor Bruschi is a retired widower who lives according to a strict routine he set for himself. An ardent old-style communist, he has always been at odds with the unconventional lifestyle led by his son and his hippieish girlfriend Stella. When their four-year-old daughter is left in his care out of the blue after the two break up, the old professor becomes a sort of father figure to the girl, growing fond of her. However he's once again challenged when Stella also arrives for a stay in his elegant villa, reclaiming custody of her daughter.
