In Florida, Kent Thurston’s wealthy friend John Blaine is being squeezed for money by “The Green Lizard,” and two of his rich businessmen friends have already disappeared. Unbeknownst to Blaine, his servant Winters is secretly working for the extortion gang (as “Number Four”), and alerts them to Thurston’s involvement on the case. Meanwhile, in another room, Blaine’s two missing friends are still alive, but now the Lizard has decided to throw them to the crocodiles. When the Invisible Hood steps into the room, the Lizard sets a 10-minute timer on a hideout-destroying bomb, and flees.
