While shooting a film in Montréal, a French actress (the luminous Monica Bellucci) tries to mend relations with her son, who after witnessing a disturbing event, has a renewed interest in discovering the indentity of his father. Elsewhere in the city, an ambulance driver tries to keep a hold on his life while a kind-hearted nurse watches over him in the chaos of the emergency room. The collision of these four leaves their lives changed forever.
