John Bunny and Henry Shayshall are attacked with "amoritis" the moment they step into Amander Witherspoon's boarding house. Henry falls in love with Flora Finnee, the "star boarder," and makes up his mind to impress her with his belated affections. He timidly places a box of perfume in front of her door. Flora simultaneously is inspired with a similar desire. Pandora, the maid of all work, sees the boxes at the entrance of Henry's and Flora's rooms. She cannot restrain her inquisitiveness and opens them. She hears someone coming and in her confusion, places Flora's gift on the doorknob of Amander's room and the box which Flora had sent Henry in front of John's room. This creates jealousy and confusion when Amander shows Flora the beautiful present she has received from John, and John shows Henry the gift with which he has been presented, as coming from Flora. The cause of the trouble is finally traced to Pandora, and to make sure, Henry and Flora decide to confirm their suspicions. They place a box filled with mice where it will come under the notice of the maid. This arouses her curiosity when she sees it. She cannot refrain from investigating, opens the box, freeing the mice, which causes her to give vent to a series of screams that brings everybody to the scene of the commotion. Pandora is "caught with the goods" and the landlady summarily dismisses her. Flora and Henry are united in love's consoling embrace and bid a "day-day" to the mischief-maker.
