Jan and Cindy are awaken in the middle of the night, scared by mysterious sounds that seem to be emanating from the attic and the vision of what looks like a ghostly apparition outside their window. Investigating, Mike and Carol discover the window in the attic open, the noise from the wind causing a creaking rocking chair to rock, and that there is nothing in the trees outside. What they are initially unaware of is that the cause of all this commotion was the boys - Peter masquerading as the apparition - who wanted to scare the girls. Ultimately Marcia believes the boys were responsible for everything, and she leads her sisters in getting back at the boys with a little of their own medicine. All this pranksterism may get out of hand, especially with a comment added by Alice. Meanwhile, Carol is sculpting a bust of Mike's head for her art class' competition.
Did You Know?
When Marcia holds up the slide of the "ghost" the hand that is holding the slide is apparently that of a woman with a manicure. When the camera pans away Marcia's hands do not have nail polish applied. See more
Maybe I left one of my nightgowns out on the line, that'd scare anybody.
