Children caught in a deadly tornado, a catastrophic car accident, a violent hostage crisis in a maternity ward. It can happen anywhere at any time. In an instant, life can change forever, and that moment will define who you are.

Returning for its second season, 20/20: In an Instant does more than just re-tell heart-pounding first-person accounts of the world's most harrowing tales of survival; it brings them to life with breathtaking dramatizations of the moments before and after life was forever changed. The powerful series features trials and triumphs from every angle and includes gripping first-person interviews with the people who lived to tell their stories, and those who were instrumental in helping them survive. These are the stories of ordinary people who have watched their lives flash before their eyes, stared almost certain death in the face and overcame it. What key decisions did they make to save their lives?
