While investigating a construction company insurance racket, Daily Sentinel reporter Mike Axford comes under attack from a bulldozer. He is rescued by the Green Hornet (who, unknown to him, is actually his boss Britt Reid). In an unusual turn of events, Axford agrees to work with the Hornet in discovering who is behind the racket. The two try to bluff their way into meeting with the organization's head. But when Mike alone is contacted about the time and location of the meeting, he decides to head off by himself to wrap up the story. Britt Reid suspects Axford may be in grave danger, and as the Green Hornet, intentionally walks into a trap to try to save his friend.
