Will, a small goat with big dreams, gets a once-in-a-lifetime shot to join the pros and play roarball – a high-intensity, co-ed, full-contact sport dominated by the fastest, fiercest animals in the world. Will's new teammates aren't thrilled about having a little goat on their roster, but Will is determined to revolutionize the sport and prove once and for all that "smalls can ball!" He has to do something he has never done before.
