La mère Christain (1998)

In industrial Lyon of the early '50s, a widowed bar-owner listens to radio crime serials, reads detective magazines, and grieves for her daughter, killed two years earlier in a mineshaft accident. Consumed by her loss and unwilling to face the truth, the bar-owner becomes suspicious of the grim patrons in her drab tavern, seeking someone to blame as she contemplates revenge.
