Recap: Trying to find older(20-30+years?) foreign film(subtitled) about a Mother who works her butt off making dinner every night for her husband and two children. They take everything for granted and don't reciprocate any of the love or effort that she puts forth. They are also very demanding and basically a bunch of A-Holes. While on vacation, she gets kidnapped(which her family doesn't seem to notice or care) and basically becomes a stripper(something about a remote control car in her routine).
Eventually, the family tracks her down and demands she become the same person she was, 'cause they are hungry and want their dinner now!! She is fed up and decides to make them their favorite dinner. She poisons them all to death.
Thanks for any help finding this.
