Sophia decides to enter herself into a charity walkathon, while Rose signs up herself, Dorothy and Blanche to babysit the children of the other participants. Once the walkathon is over, all of the kids are picked up -- except for one baby girl, who the girls fear has been abandoned.

After some gentle prodding by Blanche and Rose, Dorothy invites a fellow teacher of hers over for dinner. Once he gets there, however, the girls learn one thing about him that Dorothy failed to notice -- he's a priest.
