Ben Rolf (Reed), his wife Marion (Black), son David (Montgomery) and Aunt Elizabeth (Davis) rent a country house for the summer. The only caveat is that they have to look in on the owner's 85 year old mother who still resides in the upstairs attic. But since the elderly woman is never present, it doesn't seem to be a problem.
