First of four compilations from last year's series, featuring stories of heroism and bravery, reconstructed with the emergency services, actors and the people involved in the original rescue.

Tonight's compilation from last year's series includes the reconstruction of how a trainee pilot has to be talked down to safety following the sudden, in-flight death of his instructor. Plus the stories of a 4-month-old baby who is nearly washed out to sea as waves trap her family in their car; and the Birmingham woman who had to jump from her burning home carrying a baby in her arms.

This week: how a Sunday-afternoon stroll turned into a desperate struggle against time and tide. Two potholers get into trouble while negotiating the "black hole" 500 feet beneath the Mendip Hills. Two men on a fishing trip are at the centre of a massive search and rescue operation in the Bristol Channel. And how a Somerset farmer fought his way back to health after a tractor accident left him with a broken back.

This week: the 6-year-old boy who toppled into the gorilla pit at Jersey Zoo who was saved by one of the keepers and a local ambulance man. A rescue 500 feet beneath the North Sea when a diver's face mask shattered and the bizarre accident that left a motorist impaled on a 40 foot scaffolding pole.

Michael Buerk returns to introduce more real-life rescue stories. Including the struggle to free two men trapped in their sinking powerboat after a crash at Guernsey's World Championships, the rescue of a paratrooper dangling from a Hercules which is captured on camcorder from inside the aircraft, and in Northern Ireland an unusual and baffling agricultural accident which leaves a man fighting for his life.

Including the dilemma of a couple trapped inside their burning car in the tiger enclosure of a safari park; pictures of the rescue of three canoeists stranded in the middle of the River Conwy in North Wales; the flying accident which left two brothers each convinced that the other was dead and the doctor who was forced to improvise when a baby collapsed in Sardinia. Plus, Juliet Morris continues her report on the real life Baywatch team in Perranporth, Cornwall.

Including the nightmare accident a man had feared for 25 years and his wife's fight to save him from drowning; the complex rescue of a pilot surrounded by aviation fuel after a crash landing on a motorway; and a hop-picker trapped under a tractor in a flooded river.

Tonight, the man who came back from the dead after open heart surgery in the street; the 999 call made by a man trapped in mud with the tide rising around him; and the first aider who risked his own life to help a colleague buried alive in a hopper of acidic dust. Also, Juliet Morris meets Doreen Lawrence of "999"'s real-life "Baywatch" in Perranporth, Cornwall, and there are details of free life-saving courses in Northern Ireland.

Tonight, a Christmas walk in the Lake District that became a fight for survival fora man who plunged 700 feet down an icy fell; the actual 999 call made by a woman trapped in her flat by dense, choking smoke; also the all-night ordeal of two teenage surfers lost at sea and the race to find them.
