Commander Anne Capestan leads a brigade of the Lyon criminal investigation department staffed entirely by alcoholics, depressed, and maladjusted officers. Despite this, she manages to successfully handle the most important investigation of the moment.
Almost a year after "Le Jardin du diable" opened Season 4 in November 2025, Le Voyageur returned to France 3 on Saturday, October 31, 2026 with "Le Sentier perdu", the show's 14th episode overall. Viewers had waited a long time and they turned up for it: about 4.7 million people watched, a 29.1% audience share, and France 3 easily won the night. If you were one of them, this debrief is for you. If you missed it, add the series to your watchlist now, because this was the most daring episode the show has made.
Some background first. Hervé Korian created Le Voyageur, and it began in 2019 with Éric Cantona as Commander Tom Bareski, a police officer on leave who travels around France reopening unsolved cases. Cantona played the role for four episodes. When the time came to replace him, Bruno Debrandt, known for Caïn and for playing Brémont in Engrenages, turned down the chance to take over Bareski. He suggested a new character instead: Captain Yann Kandinsky, a friend of the missing Bareski who sets out to find him. That decision gave the show its present shape. Kandinsky is a quiet loner who lives in his van with his loyal Malinois, and he solves crimes that the official investigations gave up on.
"Le Sentier perdu" did something the series had never tried. For the first time, a serial killer gives the Traveller his case. Henri Bonnal, played with unsettling calm by Warren Zavatta, is the murderer Kandinsky chased for almost a year in the Season 2 episode "Le Roi nu". Bonnal is now in prison, and he contacts his old pursuer with an offer. He believes Jacques Augier (François Cottrelle), a man he met behind bars, did not kill his wife and two children fifteen years ago in Ruisselin, a quiet Provençal village near Marseille. If Kandinsky finds the real killer, Bonnal will tell him where he buried his own victims.
