When Vic and Willie discover human remains in a cave they are exploring, the shock waves are felt throughout Bald Eagle Falls. When Willie falls under suspicion, Erin has to do more than just make her awesome new granola bars and trail mix.

Erin's investigations reveal that there is more to the case than meets the eye, and if she is going to uncover the truth, she had better watch her step.
