In 1930s Sweden the residents of a small town are upset with the morals of modern times and travel to Copenhagen to see for themselves what is going on with this new jazz music.

The year is 1925. Mölle is the fashionable tourist destination for people of a certain class. Ladies with shingled hair, men in straw hats and white suits. At the popular guest house Summer Lust the uptight but lovesick Beda rules with an iron fist. To help her she has a lot of very good personell... and Siri. Siri works as a bartender, is obsessed with movies and not very interested in helping the guests.
