Ten-year-old Eddie lives with his mom and grandparents in a small cabin on the Queen Charlotte Islands. A year earlier, Eddie's dad took the ferry to the mainland and never returned. Eddie loves going fishing with Granddad and listening to his tall tales about the big snapper. Eddie believes if they catch such a fish, it might change his family's fortune.

Mom decides to turn their cabin into a bed and breakfast. Some of the guests appreciate island life, but many do not. When Granddad falls ill and must go away for treatment, Eddie worries that he too may not come back. Already hurt and confused by his father's disappearance, upset by the attitudes of the tourists, and now missing his beloved grandfather, Eddie goes fishing alone in Granddad's skiff. Soon he is struggling with more than the need to stay afloat.
