Britt Reid and Axford witness the hijacking of a truckload of silk. They trail the hijackers, but are ambushed and Axford is taken prisoner. Reid telephones Kato to meet him with the Hornet outfit. Masked as The Green Hornet, Reid enters the isolated farmhouse where Axford is being held, overcomes the guard, ad forces him to confess that the racketeers have gone to Harbor Road to hijack another truck. The Hornet and Kato speed after the hijackers. Will our heroic pair be able to catch the racketeers before they get away with another hijacking? Will the hijackers prove too fast for The Green Hornet?
