Billie is sent to the city by her father, who wires a friend’s son to meet his “little girl.” The city man shies at “kids,” and arranges for the housekeeper to meet Billie at the train, while he goes on a shopping tour to purchase toys for the “little one.” The maid is dumbfounded to see that Billie is grown up, and tells her of the misunderstanding, at which Billie, seeing some fun ahead, attires herself in short dresses. Her arrival is the cause of a series of most laughable situations, the butler, the maid and the man all trying to outdo the other in “playing” with the “baby.” Billie gets naughty, and has to be spanked. She must also have her bath, and there are some embarrassing moments. But the greatest surprise comes when Billie, appearing as her own lovely little self, makes known the mistake.
