Inspired by a true story, The Deepest Dig is a celebration of scientific inquiry. Caden is a young boy who discovers something buried in his backyard. His parents and teacher are disbelieving, but he refuses to give up. With the support of his next-door neighbour, Martha, he unearths the giant bones of a mysterious creature! While they comically misassemble the bones, Caden succeeds in getting his parents’ attention, ultimately bringing the family together.
