Nick (Sam Worthington) jumps onto the air mattress one building away, and grabs Englander (Ed Harris), and gets back the diamond.
He is cleared of all charges. Englander goes to jail.
Nick takes Lydia to a cop friendly bar. While there, his brother Joey proposes to Angie with a very large diamond ring, most likely stolen from Englander's vault. Nick then introduces Lydia to the bartender who happens to be his father. Turns out the funeral was staged, as well, to help in his break out, and the bellhop we see a few times during the movie is Nick's father.
