After buying a model of the Unicorn, young reporter Tintin discovers a secret message hidden inside the mast of the ship. But what does it mean? The clues start to pile up as Tintin and his faithful dog, Snowy, find themselves sailing, flying, and riding camels around the globe on an epic adventure!
Along the way, Tintin meets the hearty seadog Captain Haddock, whose ancestor sailed the Unicorn and fought valiantly against the nasty pirate Red Rackham. Does the secret of the Unicorn lie with Captain Haddock? Together, Tintin, Snowy, and the captain seek out the truth, but there are enemies and dangers at every turn. Can the adventurers solve the mystery before the secret lands in the wrong hands?
