A turbulent love, unrestrained passion, and widely publicized infidelities — these characterized the final years of Simone Signoret and Yves Montand. They were the power couple everyone knew in France and beyond, legends of the entertainment and film world worldwide.

Signoret (portrayed by Marina Foïs) is depicted in the film as an intelligent and independent woman, an actress struggling to preserve her identity and status while her husband (played by Roschdy Zem) continues, even at an older age, to maintain an impressive artistic and public career. In addition, she is forced to live in the shadow of Montand’s famous affairs, the most well known being his relationship with Marilyn Monroe.

Despite all this, the couple did not separate. The film succeeds in conveying the complexity that characterized this relationship: the conflict between great love and infidelity, jealousy, and a great deal of professional and personal resentment.
