Perry and Paul are all set to go deep see fishing on a boat owned by their friend, Scott Cahill, but when Cahill's regular customer wants the boat for the weekend they have to charter another. Later, Perry gets word that the Coast Guard has boarded Cahill's vessel looking for stolen gold. They found some of the bullion and the corpse of Karl McGovern. An autopsy reveals that McGovern was killed with a fatal dose of digitalis. Scott Cahill is charged with murder when the police theorize that he and the dead man were partners in stealing the gold.
