A couple are celebrating their wedding anniversary on a luxury fort out at sea when one is severely injured. Coastguard and lifeboat crews rush to her aid. And a lorry driver has seconds to save his life as an insecure load on another truck hurtles towards him.

A mountain biker crashes head first at a jump and an off-duty rescue worker comes to his aid, a grandmother misreads road crossing signs and steps out in front of a biker, and a group of friends on a skiing trip are caught up in an avalanche.
