This documentary follows the attempts of scientists to find a theory that can explain the cause of the mysterious weather phenomenon El Niño. Once or twice in a decade there is a shift in the normal weather patterns and El Niño brings floods, droughts, snow, and heat to places in the world that don't normally experience such events. The documentary begins by looking at the largest feature on the surface of the Earth, the Pacific Ocean, which controls most of the planet's climate during normal periods and during El Niño. The scientists look for water that is abnormally warm, suspicious wind impulses, and ultimately trade winds that change directions as signs that El Niño has started. This information is fed into a computer to create a model that is then used to predict when El Niño will occur and how intense it will be.
