In another "on the road" story arc, the Ricardos and the Mertzes prepare to vacation in Florida. When Lucy (Lucille Ball) loses two of the train tickets, she and Ethel (Vivian Vance) advertise for a traveling companion to help drive to Florida and pay expenses. The ad is answered by Mrs. Grundy (Elsa Lanchester), an eccentric health-food fanatic who seems to be in a terrible hurry to get to the Sunshine State. En route to their destination, Lucy and Ethel are confronted with "evidence" suggesting that Mrs. Grundy may be the notorious ax murderer Evelyn Holmby! Also appearing in this episode is a young, clean-shaven, decidedly pre-Cool Hand Luke Strother Martin. ~ Hal Erickson, Rovi
