They decide they need to recruit new members for the Marching Tigers. Tweet is the drum major of the band, and Mace is his sidekick and best friend. On their quest to build a band, they help students in their school deal with conflict, bullying, and emotional challenges that all children encounter. Tweet and Mace show children how to turn negative situations into positive and productive accomplishments.
