Laurent Dubois is a jeweler who manages to sell a magnificent black pearl for $4000. Turns out the buyer's wife doesn't know what to do with only one pearl and insists that they find another. Dubois returns to the pearl's original owner, Captain McCabe, to see if he can find another. McCabe feels that he was cheated on the first deal and he refuses Dubois' offer to double the original price if he can find a second pearl. Dubois eventually gets the pearl and a bit of a surprise as well.
