Bruce Lane (George O'Brien) is tasked with handing a subpoena to Commodore Selby (Brandon Evans) who is taking part in a yacht race along with his lovely daughter Betty (Constance Worth) and ends up stowing away. When he is discovered he ends up in the centre of peril when the yacht gets lost in the fog, and ends up getting rammed by a gun running cargo ship run by Captain Morgan (William Hall) who seems a bit of a rum fellow...
Bruce is rather cocky in his role but also seems to be the only person on the yacht who isn't incredibly naive. However sooner or later they all get wise to Morgan and his ship and realise they are in great danger.
An entertaining yarn on the high seas in the (latter) days of sail. The scenes aboard ship are very well done. Overall the tone is fairly light, the main characters a bit pantomime but it suits the film.
