Given a choice between traveling to South America as an emissary for his father's ammunition company and foregoing his weekly allowance, Billy Drake heeds his father's warnings and buys an ocean liner ticket. Before leaving, however, the movie-struck Billy spots a beautiful woman standing in front of a theater and imagines that she is a film star. To his delight, he finds the woman on board his ship, as well as Count Von Nuttenburg, a political troublemaker, who has stolen a movie camera, thinking that it is a new brand of machine gun. Von Nuttenburg shows the camera to Billy, who concludes that the count is a director and the ship is a set for a movie melodrama. When the boat lands at a port torn by revolution, Billy insists that the guns and soldiers are part of the show. Not until he and the girl are seized by the rebels and threatened with death, does he admit his error. By a clever ruse, he escapes from his captors and with the help of Federal troops, defeats the count and wins the heart of his pretty shipmate.
