A man was driving a lorry when it broke down. He got out of the cab to see if he could repair the lorry when a massive blast overturned it and rendered him unconscious. When he awoke, the world was on fire and he found some shelter in a partially ruined building. He remained there for some days before finally walking away to try to find other survivors. He found a small family and helped them in their difficulties. He realised then that his future mission in life was to find more survivors and help them as much as possible.
