The story opens with a pretty love scene between the Lieutenant and his betrothed, Kate Stanley. Hammond is ordered to join his regiment in Cuba and Kate is heartbroken. He tells her they must part, and the girl decides to be brave. She exacts from him a promise that he will be true to her, and not indulge in any flirtations with the dark-eyed senoritas she has been told lure men from their vows of constancy in the land of flowers. Hammond is only too willing to swear eternal constancy. Kate places in his watch case a photograph of herself, kisses her manly soldier, and the leave-taking is very affectionate. The scene reverts to Cuba, Lieutenant Hammond arrives, and is impressed with the country. Kate, having relatives in Havana, receives an invitation to pay them a visit and eagerly accepts, thinking she will meet her lover. She is apprised of his arrival at Havana, and, knowing the predilection of soldiers to flirt, resolves to investigate.
