Escape's "The King of Owanatu" is the story of a man who refuses to allow anyone to leave his island...ever.
As the episode opens, Mr. Remington and his first mate, Mr. Hacker, are sailing to an island in the Coral Sea where they believe they will find black pearls. As they approach the island, they pass through an entranceway in the reef that has suddenly appeared. When they are clear of it, they find that the entranceway quickly closes behind them.
On the beach of the island is Jerome, the "resident" of Owanatu and its only government official. He welcomes them to his island, and appears gracious, but he is not fooled by his visitors. Jerome knows where they have come from and what they want. What Remington and Hacker don't know is that Jerome has his own plans for them.
