Diane is married to Julien, an architect. The two met in Czechoslovakia before marrying and moving to France. Julien becomes extremely jealous when he suspects Diane of having a lesbian affair with a ballet dancer. His incessant questions and insane jealousy make Diane resentful to the point she considers pushing him off a cliff.
