Colin has a very pleasant life: he is rich, he loves the food his cook makes, he loves his pianocktail and his friend Chick.
One day while having lunch with Chick, Chick tells him that he met a girl named Alise with whom he has a common passion. Colin meets Chloe at a party Chick invited him to. They fall in love, marry, but Chloe becomes ill during their honeymoon. As time passes, Chloe's condition deteriorates while the relationship between Chick and Alise turns sour.
Colin spends his fortune on treating Chloe, which causes him to passionately fire his cook and sell his pianocktail, and he slips into poverty as Chloe passes away. His friend Chick spends both his and Colin's money on anything that has to do with Partre, and Chick loses his job due to a Partre-related incident and is later killed when resisting law-enforcement officers. Alise tracks down Partre himself and kills him.
The aesthetic of the film changes from colorful and whimsical to monochromatic and tragic as the film progresses. These effects are observed most acutely in Colin's home, which decays supernaturally, and his mouse, who reluctantly tolerates the house until he abandons Colin.
