In the Middle of Nowhere

Sounds vaguely like a Mexican version of "Petrified Forest." A quiet highway restaurant, run by a former union leader, his wife, and his son is invaded by three fugitives: a wounded criminal, his brother, and his mistress. They are being pursued by the woman's powerful husband. They hold the family as hostages until the inevitable confrontation but may be in for a surprise about who will confront whom. Spanish with subtitles.
