This is a long shot, but here goes…
About five years ago, I saw a Turkish film at the Museum of Fine Arts in Boston that was about an honorable man (good husband, ran a men’s clothing store) who slowly became corrupt after he found(?) a large bag full of money. The film ends (I’ll tag this just to be safe) with a scene in which he is caught in flagrante with a neighbor woman, and then he throws himself off of his balcony. I believe the film was made in the 2000s, or possibly the mid to late '90s.
Does this ring any bells? For the life of me I can’t remember the title, and I’d like to see it again.
