It is autumn and as many forest animals are settling down to hibernate, others take up their instruments to play a special winter lullaby. The forest orchestra is organised by the Dormouse, who heads off to sleep, reminding the others that under no circumstances must they wake Mr Bear. At first all is quiet but then, suddenly, a group of merry-making wolves crash into the forest. They are a lively bunch, and don't care about not waking Mr Bear - they just want to party! Their joie de vivre is infectious and it's not long before the forest orchestra have swapped their flutes and harps for guitars and speakers. It's all tremendous fun until a dark, bear-shaped shadow looms over the forest...A funny story that also teaches the importance of the rhythms of nature.
