As a juror at Jacques Viguier’s trial, Nora (Marina Foïs) is convinced that he did not kill his wife. This intuition quickly becomes an obsession. She persuades Eric Dupond-Moretti (Olivier Gourmet), the most famous lawyer in the country to defend him. Together they start a compulsive fight to prove his innocence against all odds. That quest has a price they might not be ready to pay.
