Patty and her friend Mona live at the seaside for a couple of months while their parents are off and gone to various other locations. Mona, though rich, doesn't necessarily have the good taste and social skills that she should, so Patty is trying to be a good influence on her. With Patty around, lots of people come to visit the girls, and Mona is eventually inspired to have her very own "house party," which means that a whole bunch of people come to live with you for several weeks and you have lots of picnics and dances. Lots of social doings in this one, as well as the inevitable automobile mishap (really, Patty gets stranded quite a bit!), and Patty also meets Bill Farnsworth, who begins to play a much more significant role than the other young men who come and go in her life (although she tries very hard not to play favorites).
