Kate Humble and Ben Fogle return to Longleat Safari Park as it enters the busiest time of the year. The park's 14 giraffe make their way to their summer paddock, only for baby Evan to cause a stampede. Meanwhile, Jean Johansson attempts to capture a snake-killing secretary bird in super-slow motion. There has been a baby boom in monkey jungle with 15 babies born in just three days, but elsewhere another baby is in great danger. A new reindeer calf is just an hour old but has become weak and is now unable to suckle from its mother. As the little calf begins to fade away in the arms of a keeper, can the team find a way to save this fragile new life?
