In Greece, the radar and missile systems are jammed and surveillance is intensified. When the magician Pericles and his car are searched by the authorities, a mysterious electronic black box is found. They learn from Pericles that other boxes have arrived in Greece; then he commits suicide, eating his poisoned cigar. NATO Agent Robert Ford (Christian Marquand) follows a lead and contacts a man named Alcibiades (Claude Chabrol) at the Corinth Port and he asks one thousand dollars to tell the whereabouts of the black boxes. However, he is discovered by his boss Kalhides (Saro Urzzi) and a killer (Antonio Passalia) shoots him and he falls off in the sea. Robert meets his wife Shanny (Jean Seberg) in their room at the Hilton Hotel, but is murdered by the killer that frames Shanny and she is accused of murdering her husband. Robert's chief of the intelligence, Mr. Sharps (Michel Bouquet), hits on Shanny and releases her from the prison. However, Alcibiades had visited her in the prison disguised as orthodox priest and demands one thousand dollars to tell her the whereabouts of the black boxes. Sharps does not believe Shanny and assigns Robert's partner, Agent Dex (Maurice Ronet), to keep her under surveillance. But the stubborn Shanny is decided to find the culprits to revenge her husband and prove her innocence.
"La route de Corinthe", a.k.a "The Road to Corinth" (1967), is a spy adventure by Claude Chabrol that does not work well, since it is silly for a thriller and unfunny for a comedy. The gorgeous and sexy Jean Seberg is the best offered by this movie. It is funny to see Shanny and her purse luring internation and skilled spies along the story. Mr. Sharps is a ridiculous character and the killer is funny with his gay movements. Shanny convincing the mob boss Kalhides that she wants him in the end of the plot is so naive that becomes dumb. My vote is five.
