Dick and Mary quarrel and break their engagement. Each, unknown to the other, decides to go on a sea voyage to soothe their wounded feelings. They book passage on the same steamer. After the ship has sailed, the former lovers become aware of each other's presence, but they stay haughtily aloof. Dick's small brother Georgie and Mary's little sister Carmen, who have been taken along, are squelched in their innocent desires to play together. Dan, the cabin boy, soon is "on'' to the situation. He constitutes himself Cupid, and cajoles a jolly curate into bringing about the marriage of the reunited lovers. All ends happily, thanks to Dan, for the grownups and the youngsters.
