Profiling the work of Wales's RAF Search and Rescue crews.
RAF Valley crew and their families prepare to join Prince William in the Falklands.
The Valley crew tackles dangerous low cloud in a battle to save an injured man on Snowdon.
In this first programme, Flt Lt Wales flies the Sea King to rescue a young boy injured in a quarry in Blaenau Ffestiniog. Winchman Nick Jones from Swansea deals with a serious road traffic accident on his first ever shift, and the crew need to reach two injured mountain bikers - but they're low on fuel.
Winchman Dickie Myers and his crew race to the aid of a diver suffering from the bends in the Nantlle Valley, Gwynedd. Sergeant Martin Seaward and co-pilot Flt Lt Wales - AKA Prince William - head to Anglesey to help an injured woman, and a young girl meets her rescuers at RAF Valley a year after she was in a horrific car crash in Llandrindod Wells.
