"How crazy!" A man and a woman watch episodes from Nils Poppe movies outside a cinema Maxim in Stockholm. Poppe represents, among other things, a poor composer who vainly tries to get a tune adopted by a publisher. The failure makes him depressed, but he is living it up by meeting a good friend Calle, who invites him home. Poppe stays for a few days as a male housewife. Calle has a music store and there the two friends can go crazy among all the instruments.
Dan, aged 19, leaves his home after a quarrel with his father. At the side of the country road he meets a traveling theater company who has run out of money. He falls in love with the young actress Pia and together they leave, meeting a string of peculiar characters: a vagabond, a friendly vicar and a cynical adventurer.
