Matt Baker and Julia Bradbury are in Bristol, a city with the countryside on its doorstep. Matt visits the Avon Gorge, where some of the rarest plants in Britain are clinging on to life. Julia is on a mission to find the wildlife making the city their home. She heads to the harbourside in an attempt to catch a glimpse of one of our most elusive mammals - the otter. She also meets some hardy folk from the Henleaze Swimming Club who take to the water for a winter swim. Elsewhere, the scandal of horse meat in our food has shocked us all, but Tom Heap finds out it is not the only problem when it comes to illegally produced meat being imported from Europe. And Adam's finding out what's being done to preserve and conserve one of our rarest breeds of cow.
