The third film in the saga of the unlucky clerk Ugo Fantozzi, played by its creator, Paolo Villaggio.
Accio and Manrico are siblings from a working-class family in 1960s Italy: older Manrico is handsome, charismatic, and loved by all, while younger Accio is sulky, hot-headed, and treats life as a battleground — much to his parents' chagrin. After the former is drawn into left-wing politics, Accio joins the fascists out of spite, but his flimsy beliefs are put to test when he falls for Manrico's like-minded girlfriend.
Christmas holidays on the snow of Cortina D'Ampezzo. Mario, a guy from Rome who has not much money, falls in love with the American Samantha, the girlfriend of hypochondriac Roberto. Billo, a singer and a playboy, meets Ivana: she's married with a rich man, Donatone, but in the past she had a flirt with Billo, who wants to reignite the flame.
