"Hawaii, Oslo" is the story of a handful of people who cross one another's paths without necessarily knowing one another, during the hottest day of the year in Oslo. Frode and Milla are having their first child, whom they are told will not live long. Bobbie-Pop, a faded singer, tries to commit suicide. Leon, an institutionalized kleptomaniac, is waiting for the arrival of Åsa, with whom he has a 10-year deal to get married. Leon's brother Trygve fetches Leon from the institution to celebrate his birthday, but Tryge actually plans to use this leave from prison to run away. And the angel Vidar, Leon's best buddy at the institution, sees things no one else can see and just might be able to save everyone.—Anonymous

As Oslo suffers through the hottest day of the year, the paths of several strangers cross. A male nurse believes he can sense the future (as long as he's asleep), while a suicidal former pop star pines for the past. "Hawaii" is a local bar where two long-lost lovers swear to meet to fulfill their childhood promise; Hawaii, the American state, is also the place where one lover's brother dreams of fleeing to during his one-day furlough from jail. Meanwhile, a grief-stricken married couple hope to make a desperate trip to the United States for an experimental operation that might save their child's life.—Anonymous
