The Crimson Rivers (Seasons 1–4)

The Crimson Rivers (Les Rivières pourpres, 2018) is a French crime series you can watch online on iFILM. Based on Jean-Christophe Grangé's crime novels, the show pairs inspector Niemans (Olivier Marchal) — a blunt, solitary detective from the old school — with his younger partner Camille Delaunay (Erika Sainte). Their working styles clash. So do the cases they're assigned.

Each investigation pulls them into a different corner of provincial France: mountain monasteries, industrial towns, villages where old rituals persist under the surface. The murders are brutal and carry ritualistic marks. Local police can't handle them. Niemans and Camille dig for motives no one nearby wants to admit.

The series works case by case, with each arc set in a new location. French regional culture isn't backdrop — it drives the story. Stream all seasons of The Crimson Rivers online on iFILM.
