Host Derrick Campana travels to Louisville, Kentucky to create prosthetic legs for Hanabi, a pit bull terrier born without front paws.

Derrick helps a Flemish Giant rabbit named Diego who has a front limb deformity.  Later, he revisits Chicago, Illinois to meet a 10-year old dog named Birdie, who has never walked with four legs.  Derrick is challenged with building a full limb prosthesis that Birdie will accept and use to prevent further injury to her front leg.
