Kate's cousin Mae visits and tells everyone that with some backing from a wealthy banker, she plans on turning the Shady Rest into a health farm using a diet and exercise program called the "Mae Method Reducing Course". The only stipulation for the financing is that the banker's daughter, Agnes Bedford, has to lose fifteen pounds in two weeks using the method. However, Mae can't stay as she has to go back and deal with the banker, leaving Kate to work with Agnes. Uncle Joe is all for the idea until Kate tells him that he will be the male guinea pig of the Mae Method. Agnes, who loves her food, isn't the easiest person to convert to this new way of life. Kate, the girls and Uncle Joe's kindness towards Agnes doesn't help their cause. Mae returns with a new scheme for the hotel.
