Britt's at home, preparing to go out with Miss Case when he hears on the TV a report of aliens landing. Britt thinks it's a mistake but suddenly some people who appear to be from another planet come in to his house. And they make demands among them is for him to call Scanlon to clear the road so that their space craft can land and pick them up. Scanlon does it. They then leave but take Miss Case. They knock Britt and Kato out. Scanlon later shows up to tell them that he just heard that a military convoy is on the road they cleared carrying a warhead. Britt turns into the Green Hornet and follows them. He suspects the leader is not an alien but a disgruntled scientist and he plans to get the warhead.
