A mother and son are helped by neighbours when an out-of-control car smashes into their house. A couple have a lucky escape whilst driving, as a lorry sheds its load while rounding a bend at speed. And a biker must make a split second decision on a busy roundabout.

A young mum, alone at home with her three-year-old daughter, has a life-threatening asthma attack. Elsewhere, a coastguard helicopter lowers a winch to a swimmer who has clambered 50 feet up a crumbling cliff face, but the aircraft's downdraft makes the rescue hazardous.
