This fifth entry in Universal's "Ma and Pa Kettle" series finds the Kettle family taking a trip to Paris (courtesy of the Universal back lot). All the standard "innocents abroad" gags are in attendance, including Pa Kettle's (Percy Kilbride) efforts to extinguish a flaming serving of crepes suzettes, and Ma's (Marjorie Main) entanglement with a team of Apache dancers. Somewhere along the way, the Kettles agree to help the American authorities trap a gang of international spies. A running gag finds Pa Kettle trying to purchase a set of postcards depicting "zee beauties of Paree." There's even a throwaway joke about the Marshall Plan! Sharp-eyed viewers will spot Rita Moreno as a nightclub chanteuse in one scene. Of the nine "Kettle" programmers produced by Universal, Ma and Pa Kettle on Vacation is arguably the most memorable.
