    In Rio , one of the points of attraction is doubtlessly the most famous beach in the world, the Copacabana. When the weather is right the Copa becomes a stage on which everyone can play a part. Rio’s beaches, however, are bad news for swimmers. The surf is so striking. Often careless or over-courageous tourists must be pulled out of the water by a rescue(救援) team. In peak season during January and February, the helicopters of the governmental rescue organization, fly life-saving tasks from sunrise to sunset. Doctors also need to be on board when the control room reports an emergency(突发事件). The doctors and rescuers will do their best with the equipment available on board. If the patient shows no signs of recovery, the  rescue team decides to fly him to hospital.

In Rio, lifesaving is a man’s job. The four-meter-high watchtowers are always manned. Alarm at tower number 5, a woman has swum too far out to sea and can’t make it back to the beach by herself. One minute later the rescue team has reached the Copacabana. From a height of ten meters above the water, Luis Carlos jumps into the sea close to the helpless swimmer.  His workmates on board must keep an eye on him so that they can tell the pilot in which position to keep the helicopter. Another man is in the water now to help calm the woman down and get her ready to be airlifted. The pilot must slowly control the helicopter sideways and aim carefully. Once the net is full, the helicopter slowly flies to the beach.
