Derrick and his sidekick, Henry, travel to Mooresville, North Carolina to build a custom cart for Boots, an 11-month-old corgi who was born with front limb deformities. The Russell family have a special place in their hearts for special needs dogs. Boots’ sister Buttercup, is a 6-year-old corgi who lost her mobility three years ago, and has been using a cart ever since. Buttercup’s favorite thing in life is to chase a ball and Boots has never had the chance to join in. Derrick and the Russell family are eager to see if Boots will accept the cart and race alongside his sister.
