As the sun rises in NYC on the morning of September 11, 2001, the day seems no different. As random as random can be, 5 individuals step into a crowded WTC elevator. When the elevator stops on the 34th floor, it empties leaving only these 5 persons behind. Moments later, the world changes ... their world changes as the collision of a jet into the North Tower incapacitates the elevator. With no understanding of what has happened and is happening around them, these fives are forced to band together and fight against all odds to escape from the impending horrific collapse. Gina Gershon comes to BUILD to discuss her role in the new film, "9/11."
