Everyone is asleep at the start. Caviezels character wakes up first. He checks to make sure everyone is alive and then decides to walk around and try to find out what is going on. He discovers that all the windows have bars over them and the only door has a mechanized lock. He finds a ringing phone and picks it up. The caller asks what is going on and Caviezel tells the caller that everyone is fine. The Caller tells him he will be back in a few hours. Meanwhile, somewhere else a money drop off is going down. Mr. Coles has been kidnapped.Back in the warehouse, as the others wake up, Pantolianos character asks to be untied. As Caviezel is going to untie him, Peppers character convinces him not to, telling Caviezel that Pantoliano is obviously not on the same side as them or he wouldnt have been tied up. As Caviezel and Pepper start looking for the keys to release Sisto from the handcuffs and treat his wound, Kinnear wakes up and gets into a fight with Caviezel and Pepper. Back at the drop off, the signal in the money bag goes silent and the cops rush in to find the money gone. ........
