Dust, sand and shimmering heat – it is the dry season in Tsavo. The drought makes life difficult for many creatures. Without the precious water there is no long-term existence - the few water points are all the more important.

The first episode describes how the rare but heavier rains affect the flora and fauna - and how a waterhole is created. It all starts with an abandoned termite burrow. The building material of the crumbling tower magically attracts elephants because it contains mineral nutrients that enrich the gray giants' diet. And so the elephants, as well as wind and rain, completely remove the termite burrow over time until a shallow depression is created.
