A sporting goods store offers a prize of a complete archery set for the organization that puts on the best play. Den 1 and Den 2 plan to put on a play as a joint effort in hopes of winning the prize. The Cubs decide to put on a production of Robin Hood and receive permission from Mr. Kain, who works for the bank, to use a property known as the Haunted Castle as the setting for their production. All appears to be going well until the Cubs are accused by Mr. Kain of breaking a window and setting a fire. Mr. Kain orders them to pay for damages or leave the property.

The Cubs have seen someone hiding in the bushes on the property, but since they have no proof, they pay Mr. Kain so that they may continue to work on the play. As the Cubs finish working on their play, they investigate the bank’s property, hoping to meet the trespasser and prove their innocence of any wrongdoing. In time, the Cubs learn the identity of the trespasser and exonerate themselves. Additionally, they help a new friend become a Cub Scout.
