Les Secrets du Finistère - Le Chant des sirènes

Les Secrets du Finistère: Le Chant des sirènes (2024) is a French TV thriller you can watch online on iFILM. A woman is found dead on the coast of Finistère, her body arranged in a way that mirrors ancient Breton mermaid lore. Commandant Jérémi Lobier doesn't believe in folklore — but the case won't budge, so he calls in Morgane Le Dantek, his former colleague turned professor of Breton myths.

Directed by Jean-Marc Thérin and starring Évelyne Bouix and Jérémy Banster, the film uses the granite coast and Celtic legend of western France as more than atmosphere. The mystery earns its supernatural framing by keeping the resolution grounded. Stream it online on iFILM.
