Sinbad, after wasting the fortune left to him by his father, decides to recoup his wealth by going to sea. He and his companions land on what appears to be an island, but the island proves to be a gigantic sleeping whale on which trees have taken root. A fire kindled by the sailors awakens the whale and causes him to dive into the depths of the sea. Sinbad is washed ashore on a different, densely wooded island, where he comes across one of the king's grooms. When Sinbad helps save the King's mare from being drowned by a huge sea horse, the groom brings Sinbad to the king. Rewarded handsomely by the king, Sinbad returns to Baghdad to resume a life of ease and pleasure.
