Nature's Weirdest Events

Chris visits the town that was brought to a standstill by a swarm of flying insects, as well as meeting the polar bears whose bizarre friendships shocked a community and the sleepless residents kept awake by a lover's deafening serenade.

In the second episode, Chris looks at events that stop us in our tracks, invade our world and disrupt our lives. He travels to a village awash with billions of tiny crabs, meets people who faced an angry mob of elk and visits the town that woke up to an apocalyptic sky.

Chris looks at some of the most extraordinary behaviours and extreme adaptations that animals have developed to survive. He discovers the secret of a frozen frog that can bring itself back to life, unmasks the slimy character responsible for mysterious oceanic ooze and delves into the underworld of real-life zombies.
