In order to say goodbye to his dying mother, an exiled gangster turned priest must finally face his past.

That's a good first half of a logline, but you stop right when things get interesting -- Tell us what he must do, what he must overcome in order to say goodbye to his mother. The stakes are clear, as is some urgency with the ticking clock of her imminent death. There's also some great irony in a gangster turned priest, we're just missing that last element so we can accurately see this movie in our mind.
