Delia, a young Romanian girl, comes to Bucharest with her parents to collect a prize she has won in a contest organized by a soft-drinks company. The prize is a beautiful new car. All Delia has to do now is appear in front of the camera in a commercial. All goes well until it becomes clear that Delia and her parents have very different ideas about what to do with the new car. Meanwhile, the contest's sponsor needs a radiant prize-winner with a gleaming smile. A wicked satire and a psychological portrait of a society perverted by its slavery to capitalism and consumerism
Unfortunately the movie The Happiest Girl in the World is not yet available on HBO Max.
