Out of love for a beautiful passenger he met on a crossing, journalist Robert Vitrac agrees to deliver a letter to a man named Pablo. A dangerous mission, since the beautiful Manuela has had in her possession the proceeds of a robbery, which she must forward to the fence. In this game, Vitrac would lose his honor and perhaps his life if Inspector Berio's friendship didn't protect him. Manuela, who seemed sincerely in love with the journalist, falls victim to the bandits.
