Lucas (Vincent Lindon), a successful businessman, falls in love with Elsa (Sandrine Bonnaire), an artist who's been commissioned to paint a mural in his office building. Not trusting his heart, Lucas asks his company's head of security (François Berlléand) to trail her. When the three get tangled up in the latest surveillance technology, Lucas's clever plan blows up in his face. Pierre Jolivet directs this romantic comedy.
