After running into a group of hikers, Nancy asks if they've seen anyone, only to find that one of the hikers is also the thief! When Nancy breaks off from the group to make a phone call, she is pushed from behind and ends up dangling from a tree root, afraid to call for help lest the crook find her. This time, its up to Bess and George to help their dear friend Nancy Drew.
