When Dorothy looks for extra work to do during the summer, Blanche gets her a job at the museum where Blanche works. However, Blanche soon becomes jealous when it seems Dorothy is more proficient at her job than she is. Meanwhile, Rose finds a stray dog while shopping.

A dateless Rose puts an ad in the personals column, then feels even more dateless when she doesn't get a response at first. Soon, though, she begins receiving letters from someone named "Isaac Newton" -- but Blanche confesses to Dorothy that she's the one who's writing the letters. Meanwhile, a 90-year-old British man takes an interest in Sophia.

While attempting to fly to their respective families for Christmas, the girls' plans hit a snag when a depressed man in a Santa suit takes them hostage at the grief counseling center where Rose works.
