A penniless countess falls in love with a cad, unaware that he is also involved on the side with her beautiful daughter.

The Resonator, a powerful machine that can control the sixth sense, has killed its creator and sent his associate into an insane asylum. When a beautiful psychiatrist becomes determined to continue the experiment, she unwittingly opens the door to a hostile parallel universe.

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).
