Troubled Water. It's a Norwegian movie, so not a lot of people have heard about it, but God is it good. It's about a guy who accidentally kills a kid in a robbery gone wrong and goes to prison. When he is released he goes to work in a church as the organ player. He is a deeply troubled man and is haunted by the child, and his music is stunning. The movie is deeply moving and sad, and deals with redemption and loss. It's more of poetry and art than a mere "movie." Keep in mind there are two movies with the same name so I put a pic, both are on Netlflix.
