Unbreakable

David Dunne a security guard was traveling to Philadelphia from a train with 132 passengers on board. The train meets with an accident. To his surprise he is the only survivor and not only is he alive but even unharmed. He was trying to juggle with this truth, when he encounters a mysterious stranger Elijah Prince (Samuel L. Jackson). He explains him that he is “unbreakable”, having extraordinary fortitude and courage, a tendency towards dangerous behaviour. David does not believe to the words of Elijah, but when he recalls his past life and realizes that he has never been sick or hurt, also he is more physically strong than a normal person. Is he really “unbreakable”, but he might have to pay the price for being unbreakable?
