One day Scrooge is at his Money Bin counting his morning assets, when Huey, Dewey and Louie show up, reminding him to get ready to go on their fishing trip. Before he can leave, a worker informs him that one of his cargo ships, the Queen of the South, has gone missing in the Bermuda Triangle. Scrooge is aggravated, as this is the third ship of his to have gone missing in the Bermuda Triangle in the past two years. Scrooge decides to find out what happened first hand by heading to the Bermuda Triangle himself, with Huey, Dewey and Louie tagging along for their fishing trip.
