Bobby Hillard, inspired by his neighbor’s arrowhead collection, pesters his mother all summer to allow him to join his neighbors Charlie and Lester on their daily hikes along the Delaware River so he can search for his own arrowheads, but his mother always says no.
At the end of summer, Bobby’s mother finally says yes, and Lester shows him how to search for his treasured arrowheads, but the task is more difficult than Bobby realizes. Feeling sad and discouraged after searching for hours, Bobby decides to rest under a tree. He then receives a message from Indian Chief Nomad, who seems to appear before him, telling him to keep looking. Will Bobby understand the message and find his treasure, or will he give up and go home empty-handed?
