In Caro papá, Dino Risi is telling the story of the decadent lifestyle, and dysfunctional family, of a wealthy businessman (played to perfection by Risi's favorite leading man, Vittorio Gassman). Risi paints his portrait against a backdrop of an Italy where the new permissiveness has run rampant, traditional socio-cultural values have been usurped by consumerism, and the streets have become an open battleground for politically extremist groups (the '70s were dubbed "The Years of Lead" due to the great number of terrorist acts, and politically motivated assassinations).

When political thugs murder an opponent's volunteer and also kill a cop, chief inspector Verjeat believes the politician who hired them is as guilty as the murderous goon. Verjeat's pursuit of the councilman, Lardatte, gets him a warning from his superiors. When he embarrasses Lardatte while disarming a hostage (the dead volunteer's father), Verjeat is told he's being transferred within a week. He speeds up his hunt for the goon and, with Lefévre, one of his young detectives, he engineers a complicated scheme to buy more time before the transfer. How should Verjeat play out his values of honor and duty?
