I saw this as a child. All I remember about the movie was that it had a futuristic Sci-fi feel. It was set in space aboard a ship I believe. The main characters appeared humanoid but they had wings rolled up under their capes which then unfurled only when necessary.
In one scene, a boy was supposed to disarm a weapon and was shot many times in the back destroying his wings and killing him after he disarmed the weapon.
