O Comissário Maigret (Gérard Depardieu) investiga a morte de uma jovem de vestido de noite encontrada numa praça parisiense. Nada permite identificá-la, ninguém parece conhecê-la. Durante a investigação, conhece uma jovem delinquente que se assemelha estranhamente à vítima, despertando nele a memória de outro desaparecimento, mais antigo, que lhe deixou marcas profundas.
Baseado no romance de Georges Simenon.
