The pair share a birthday and desperately want to spend it together. The story follows Little Dot as she tries everything to hand-deliver a special card to grandma Dot in New York: she tries to bounce on springs across the ocean; asks birds and butterflies to help her fly; and even digs a tunnel in her back garden. Meanwhile, Grandma Dot is making a surprise trip to London, but travels the long way round. At each stopover, in Beijing, Mumbai and Rome, she gathers family and friends and buys a mystery present for Little Dot. But will Grandma Dot arrive in London in time for the big day? And will Little Dot be there?
