When an Algonquin Indian named George Longbow crashes a town party, he hands Mayor Booth a land grant that claims he and his people own the land that Cabot Cove was founded on. Suspecting that Mr. Longbow's claims are false, the town leaders turn to the local expert on Indian History for insight. However, when the professor confirms his claims, several business owners fear an impending development project will no longer be able to proceed as plan. At this point, when the leader of the project is found murdered with a spear in his chest, Jessica has to prove George is innocent in the crime.
