A Long Lost Silence (2022)

From IMDB:

During the summer, Jules, 10 years old, is welcomed by a young couple in the countryside, because his mother had an accident. How to feel at home in a village where its inhabitants are shaken by deep antagonisms?

From MHz Choice:

French thriller about a 10-year-old boy encountering secrets among the people who’ve taken him in for the summer.

From MHz Choice you can stream this 3 episode French mystery thriller. Each episode lasts no more than 55 minutes.  The French title is “Les Hautes Herbes”. English subtitles are provided.

Jules, the 10 year old center of attention, hardly ever speaks. But his glances and stares speak volumes as he watches the adults around him misbehave in various ways.  When episode 3 reveals the killer, things get very tense.

Lots of contention between characters and  emotional scenes make this very French film watchable.
