When Suze, a hairdresser in her mid-forties, learns that her life could soon end, she sets out to find the child she gave birth to at the age of 15 and had to give up for adoption. In the process, she meets the brilliant programmer JB, who, at fifty, was supposed to have been disposed of and who, in his indignation, has so unsuccessfully killed himself that his suicide attempt is interpreted as a rampage. The strange team is completed by the blind archivist Monsieur Blin, who contributes a mixture of genuine flashes of genius and abstruse inspirations to the research.
