Rose Beanie is a fifth grader in her last week of school. Together, she and her three friends, Molly, Albert and Archer, create a project that they call the best summer adventure ever!

During their summer, the four friends learn how to care for four farm animals: a chicken, a pygmy goat, a cow and a miniature donkey. Also, a couple of things go missing. It is up to them to solve the mystery together.

At the end of the summer, they share their project with the town and it is a big hit!
