Filmmakers follow a pride of lions, a cheetah with her cub, and a leopard family in Kenya's Masai Mara.

Torrential storms turn the short grass plains into a quagmire, and the Big Cat Diary team can only hope that the rains will stop so that they can continue their vigil after sundown.

Kidogo, the cheetah, and her cubs groom themselves; Kidogo hunts while the cubs play; how Half-Tail, the leopard, lost her tail.

After four weeks of filming, the cats are becoming more familiar and the team capture some wonderful footage of Half-Tail the leopard and her cub hunting and playing. The female cheetah, Kidogo, searches for food for her two young cubs.

Simon and Jonathan study the cats' habits; Half-Tail and her cubs become more mobile; the lion pride reappears.

The heavy rains disperse the prey on the Masai Mara; hungry lionesses and their cubs face uncertainty.
