Mavis is not like her adventurous friend Marge. Mavis is a chicken who finds EVERYTHING scary (night-time and daytime and anything hairy!). So when the slumbering peace of their cozy barn is disturbed by someone trying to steal their friend Sandra the sheep, will Mavis be able to find her bright spark of braveness and save Sandra? With a tractor, a lasso, and a lot of -durance, Mavis might just have what it takes to be the hero the barn needs.
