I can’t remember the name, but there’s a documentary similar to this. It’s about two brothers. One gets into an accident and loses his memories. His brother helps him piece it together but omits one thing: Their mother pimped them out when they were young children to her friends frequently and was extremely abusive. He doesn’t want his brother to have to live with the memories of it like he does. And the brother knows something happened but he won’t tell him. They’re older too and it’s really heart breaking.
