Angel (Audrey Tautou), a girl from the art department, falls in love with Louis (Samuel Le Bihan), a cardiologist, but the other party is already married and is indifferent to Angel, but Angel is always silently guarding Louis, firmly believing that their true love will overcome all dangers and obstacles and end up together. Louis's love was not faithful. After letting Angel down again and again, he finally returned to his wife. Angel, who could not stand the blow, turned on the gas and committed suicide on impulse. Angel was rescued by Louis, who arrived in time, and when they woke up, they found that the love was not what it seemed, and there was something else behind everything.
