Speed Kills: SEASON 1: EPISODE 1
The open plains of the Serengeti are the perfect playing ground for speed, and they're home to the fastest animals on the planet. Some are built for explosive sprints, others for marathon runs. But all of them, predators and prey, need to move fast in order to survive in this unforgiving environment. Enter the African grassland, and discover how cheetahs, hyenas, hawks, crocodiles, and other assassins of the savannah use their evolution-perfected design mechanisms to kill with lightning-fast speed.
