Through a series of trials and adventures, the youth learns to adjust to his rough new life and, with the help of his friend, the captain's son Dan Troop, he makes progress. Eventually, the schooner returns to port and Harvey wires his parents. They rush cross-country by their private rail car, given priority over commercial traffic, to Boston, Massachusetts. From there they go to the fishing town of Gloucester to find that their son has matured to become an industrious, serious and considerate young man.
