Paul Exben (Romain Duris) is a handsome and successful thirty-something Parisian corporate lawyer with a beautiful wife, two children, and a glimmering future as a partner in the firm he co-owns with his mentor, Anne (Catherine Deneuve). But behind this deceptively perfect bourgeois facade lies a restless spirit who despises his conformist life and envies the creative freedom and fulfillment of his neighbor Greg (Eric Ruf), an uncompromising photojournalist. Greg's unexpected death throws Paul's life into chaos, and he makes a startling decision that pushes him into unknown territory. Embarking on a cross-continent odyssey of self-discovery and reinvention, Paul experiences what many have wondered at some point: is it possible to become someone else?
