Paris. Marie-Lou and Mari, two women who share the same name. A once-in-a-lifetime encounter of souls.

Marie-Lou Fontaine, director of a nursing home in the Paris suburbs, defies convention by adopting the 'Humanitude' method despite her team’s resistance. Her encounter with Mari Morisaki, a terminally ill Japanese playwright, transforms her life. Together, they turn the facility into a symbol of resistance and humanity against the system’s limits.
