Plein fer (1990)

The Italians have bocce ball, and the French have a similar game, boules. This is played (generally in the southern part of the country) with steel balls on a packed-earth court. While these games have a bucolic, countrified and even genteel air about them, competition and betting are fierce. In this sports/crime thriller, a young man whose father was killed for violating the unspoken roles of the game in professional competition trains with his grandfather to become a champion boules player just like his father.

Unfortunately the movie Plein fer is not yet available on HBO Max.
