Life on the rolling main and danger in a roaring mining camp of 1848 are coupled in an agreeable adventure yarn. Sixteen-year-old Sam Endicott and his pal Steve Rogers were horrified when the crew of the Annie , bound for Sen Francisco, took over the ship from stern but just old Captain Thorn, forcing him to agree to anchor off California to allow them to skip ship and do some prospecting at the heighth of the gold fever. However, Captain Thorn agrees to the plan and even joins the company to mine in the Sacramento Valley. The cooperative endeavor almost causes disaster, and there are several deaths in the lawless area, but the remaining hands return gratefully to the ship, and the captain divides his own strike money among them. Rugged manoeuvres for young males.
