Britt Reid and his co-workers are rejoicing over the report that the oil well they helped John Fulton finance will prove a gusher. Fulton, bursting into Reid’s office, tells him that Cain, a lawyer who held his note for $10,000 changed the due date and attached his oil well. Disguised as The Green hornet, Reid forces Cain to confess he altered the note and gave it to Galt, now at the well. The Hornet goes to the well and a terrific battle ensues. Will Galt and his men overtake The Green Hornet? Will Fulton recover his losses stolen by the crooked lawyer?
