Grand Central Station, New York City, 11 pm. Gunshots and explosions fill the air, and suddenly you - and everyone else - are running for your lives. You stumble across a dead man slumped against an open locker containing a bag full of diamonds. What do you do next? Do you ignore what you"ve found and run with the rest of the fleeing crowd? Or do you take the bag knowing that it will change your life for ever, leaving you rich... or dead?
