A sea plane carrying Tintin (voiced by Adam Howden), Captain Haddock (Lewis Macleod), and Tintin’s dog Snowy is flying through a thunderstorm when it is hit by lightning and crash lands in a desert, knocking all three unconscious.
The game then flashbacks to the previous day, where Tintin and Snowy are looking around a market. Tintin purchases a model ship, which another man tries to purchase from him, but fails. The man who sold it to Tintin then brings him to a ship expert, who tells Tintin that the ship is a model of the Unicorn, a galleon which belonged to Sir Francis Haddock. From a book given to him by the expert, Tintin learns that the ship (which was a part of Charles II’s fleet) was on its way from Barbados to Europe when it was attacked by pirate Red Rackham. Rather than allow The Unicorn to be boarded, Sir Francis scuttled the ship and fled.
Tintin takes the model to a back alley to examine it, finding a scroll hidden inside, which contains a strange poem about three ships. Suddenly, he is attacked by some men, who steal the ship, but not the scroll. Tintin is able to use Snowy to follow the scent of one of the men, leading to Marlinspike Hall. There, he meets the man who had attempted to get the boat in the market, one of the Bird brothers. The brothers chase after Tintin, attempting to get the scroll, but they are knocked unconscious by a man named Allan (Timothy Watson) and his men. Allan then knocks Tintin unconscious as well.
Tintin wakes up on a ship, the Karaboudjan, but is freed by Snowy. Realising that Allan has stolen the scroll, Tintin sets out to find him. However, he inadvertently climbs into the cabin of the original captain of the ship, who gives Tintin directions on how to find Allan. Tintin confronts Allan, who reveals that he is in possession of both Tintin’s scroll and the second scroll, and that the former captain is a member of the Haddock family, an ancestor of Sir Francis. Tintin manages to get the scrolls from Allan and brings them to Haddock, who agrees to tell Tintin the story of his ancestor.
