When Nimbus escapes yet again, Mattie and her friends have to go after him … into the snow.

Following a trail of three-paw prints they discover a new friend to rescue, a farmer in need of a farm dog and the answer to making the village feel friendlier than ever – just in time for the Christmas lights to come on!
