“Coyote Lake” (*** out of four) was a potent border melodrama about a teenager (Camila Mendes) and her overbearing mother (Adriana Barraza) who run a bed-and-breakfast along the U.S./Mexico border but two guests arrive in the middle of the night threatening everyone’s safety and they have to try to outsmart them and at the same time find their personal and criminal motives for this. Interesting and intriguing story harks back to early-day Sam Peckinpah and keeps its grip thanks to Mendes’ stirring lead performance through occasional lulls. Final third is particularly strong as many of the characters’ lives and fates intersect.
