This is one of Ellen Burstyn's best performances. She is the mother of a young Canadian man who disappears while driving across the US. She hires a private detective to find out what happened because of the inaction of Canadian and American authorities. I won't say anything about the story, because it is a mystery. It is based on a true story. The final five minutes cap the story perfectly. Worth watching. I've seen it twice.
