One day, Claudio Verona, a young and successful businessman was trapped in his office elevator alone. He was on his way to attend an important business meeting with a client. He tried getting help by calling his wife, Lorena on his mobile, and also speaking through the lift communications to the building maintenance technicians. However, for a very long time, no one seemed to come to his assistance. Slowly losing his patience, he pried open the door to the lift but the width of the opening was too narrow and he couldn't get out. Therefore, he remained stuck inside the lift and isolated to the outside world.
