All of a Sudden
“One night. Two strangers. A lifetime of questions.”
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.
