Captain Abercromby was a puppet series about a boy named Abercromby, who is raised by his grandfather. After hearing the tale of how his Grandpa lost his watch, which was given to him by Abercromby's mother, he dreams that he is a captain of a seaship, the "Hope", and that he is on a mission to find the watch. They have a rival crew attempting to find buried treasure, run by Captain Jake in his ship "Thunderbottom", who mistakenly (but logically) believe that Abercromby is looking for buried treasure, so making the series a race between the two ships.
