In 1930s Prague, a Czech cremator who firmly believes cremation relieves one from earthly suffering is drawn inexorably to Nazism.

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.
