Part 3/8:
Moments before their trip begins, Sam is directed by his boss, Dennis, to find his colleague, Nathan, and board the bus. As the bus travels over a precarious construction bridge, Sam experiences a strange sensation, which escalates into a catastrophic premonition of death and destruction. When the bridge begins to collapse, Sam's frantic warnings enable him and a few co-workers, including Molly, to escape, while others tragically fall victim to the disaster.
