When a meticulous hitman kills the wrong target, he is wounded and has only two hours to figure out who betrayed him before the Mob takes its brutal revenge.

You getting in there mate. Just one thing – why two hours? Does two hours playing any important role in your story? Is a bomb set that way? Or mob gave him ultimatum that he has to come to him or he shots his daughter in two hours?

If you don’t have such a thing in there, then its an irrelevant fact and you can cut it out, making it shorter. Or add what’s at stake? What’s the mob’s revenge? How the mob finds him and kills him? How the mob wants (or how is he able to) track him down and kill him in two hours.

When you point this one out, you got it.
