Wildlife documentary featuring the fascinating lives of Britain's beautiful butterflies filmed in exquisite detail and also a celebration of their enduring appeal to the British people. Butterfly-costumed carnival-goers dance at Notting Hill, street artist Nick Walker uses their image to brighten bare city walls, burlesque dancer Vicky Butterfly recreates butterfly dances and at Britain's biggest tattoo convention women reveal their butterfly tattoos. Britain's butterflies have never been so threatened, three quarters are in decline.
