A favorite fall sport sends Tank and Silly to the park, excited to begin the play. Bouncing, hopping, racing through spectacular piles of leaves, these two best friend pups were having a great day...until...a curious sound shifts them into spy mode, and a new adventure begins. In short order, they meet the River Rescue Team, a band of ragtag rescue pups, as they travel in the River Rescue Bus to SunnyHeart Manor, making the world brighter for others who can no longer live on their own - those who love all the "rescue" attention they can get. Tank and Silly realize how lucky they are to have a home but hope they can continue to travel with the rescue team. Bringing smiles and joy to others is definitely one fine adventure.
