Two friends (Toto and Magnani) live by their wits working as comedians and cabaret at Cinecittà, before being invited to friends' parties or masked balls during New Year's Eve in Rome. The two, however, even though they make people laugh all the time in public, live an inner conflict, namely that the two have always to be aware to give a smile to someone, but they can never be rich and happy because they are street artists and with a precarious wage.
