Rosie the goat sets out to make her dream of running with the horses come true. She gets help from animals around the farm along her journey. Aiden the goat breaks through the fence so that Rosie can get through but gets his horns stuck. Hazel the sheep encourages Rosie, and Toby the donkey helps Rosie hide from one of the farmers. Rosie makes it to the horse pastures to run with the horses. When the sun is setting, farmer Simon finds her with the horses. He stops her and gently leads her back to the goat yard. He explains that she has a good life in the goat yard and should be thankful. She realizes it is a wonderful place to live. After all the excitement, Rosie curls up to take a nap and dreams about making it to the horses again the following day.
