Suggest a movie title for the following movie plot: In New York City, Nick Cassidy (Sam Worthington) checks in to the Roosevelt Hotel under the false name of Walker, goes to his hotel room on the 21st floor, and climbs on the ledge, apparently ready to commit suicide. The crowd below calls the police, with Dante Marcus (Titus Welliver) controlling the crowd, while Jack Dougherty (Edward Burns) tries to talk with Nick.

They set off the alarms, tricking Englander into retrieving the diamond and ambush him, stealing the diamond at gunpoint. Meanwhile, Nick's ex-partner, Mike Ackerman (Anthony Mackie), arrives at the hotel with evidence that Nick is planning something and demands to be allowed into the hotel room. Lydia does not trust him, and Dougherty backs her up. Ackerman claims he has found bomb schematics in a storage unit Nick rented and is convinced that he will detonate an explosive...
