Chris and Gitti are a mismatched young German couple involved in a tense, dynamic relationship. He's a tall, pasty, good-looking, charming but distant guy with a weak chin and a worried expression; she's small and robust, a blunt, childlike, free-spirited, boisterous bundle of nervous energy. They are a couple struggling for definition against bourgeois norms, and the film examines their relationship in the petri dish of a vacation at his parents' haute-bourgeois, kitsch-stuffed Sardinian villa. Alternately loving and bickering with each other--and apparently thinking this makes them unique--their relationship is cemented with invented private riffs on a shared sense of humor. An encounter with a former schoolmate of Chris's and his wife prompts changes that may be good, or may spell out the warning in the writing on the wall.
