The return of the programme featuring extraordinary eyewitness footage filmed by members of the public, who share their memories of these experiences. This edition features a kayaker who was trapped behind a waterfall in Mexico, a barber who pulled a driver from a burning car in Las Vegas, and a family who narrowly escaped a doomed ship in Greece. Plus, former downhill mountain bike world champion Gee Atherton recalls a fall from a mountain in Wales that nearly cost him his life. Narrated by Roger Allam.
