Par accident

Isabelle Blanc, a 30 years old biologist who works at the university, awakes in an hospital and doesn't remember why she is in the hospital.Little by little the doctor explains her that she had an accident driving by night under the rain and that accident provoked the death of a person.After her work Isabelle met her companion Vincent and then went alone by car: Vincent called her by cell phone, they spoke about their future and Vincent wanted that Isabelle listens to to a song; then came the crash.After going with Vincent to the place of the accident (where she saw a bouquet of flowers for the dead person) Isabelle reads in the newspaper the death notice of Marie Delhomme.
