Plot: Nick Knowles presents stories of people who have been on the brink of disaster and lived to tell the tale, all captured in recordings from the time, including how two little girls dialled 999 and saved their mum after she fell from the loft. Plus the stories of two cousins climbing a sea stack when one plunged 60 feet onto rocks and a trucker who came face to face with another lorry as he went round a bend on the same side of the road
