Jimmy Olsen and his new found friend Pug Flanagan have inadvertantly found themselves as stow aways on the fishing boat owned by Carlos. The boys sabotage the engine in hopes of buying time to get away, but Superman arrives in time to rescue them, and get the treasure map back as well. Gee, he’s a swell guy.
Later, as the ship is about to steam away, Clark gets a telegram warning him not to sail on this ship. Is it just a feeble attempt from Carlos to get them to stay on shore? Or is there more menacing threats afoot?
