Lillie's parents are caretakers of the property adjoining Mr. Montgomery's estate. He is a wealthy bachelor. Lillie's pleasures consist in shooting, boating and gathering flowers, while roaming through Mr. Montgomery's woods and gardens. Cobbs, the grouchy gardener, has orders to keep all trespassers off the grounds and in vain to keep the troublesome Lillie away. Jack, the owner's nephew, arrives on a visit, and starts out to frighten away the trespasser, but instead falls in love with Lillie and she introduces him to her parents. A pleasing romance follows and the young people get a bead of fun out of fooling the old gardener and Mr. Montgomery, but Jack always reports that the little trespasser cannot be found.
