Kan du vissla Johanna?

Every Christmas Eve since 1994, Swedish television has shown this film, which first aired on 24 December that year. Berra (Tobias Swärd) has no grandfather, and he wants one who is kind to him and can teach him to whistle. His friend Ulf (Jimmy Sandin) knows where to look, so the two boys go to a home for senior citizens, where Berra settles on Nils (Per Oscarsson).
