 As they ride through the forest, Jim West and Artemus Gordon notice the unusual lack of vegetation and animal life. They are suddenly approached by a giant knight who takes them to a large tent. There, West and Gordon meet a miniature Robin Hood, who is really the evil Dr. Miguelito Loveless in disguise. Loveless wants to control the Indians as he starves them by killing their food with his lethal green powder. Jim and Arte learn that this is a prelude to the diabolical Doctor s next plan, which is to drop the poisonous powder over Washington D.C.
