Persuading his newlywed friends, Jerry and Marian Townsend, to take him along on their European honeymoon as guide, Lester Aloysius Sebastian Brown launches the threesome on a series of comic adventures, beginning in a Paris nightclub, where Lester is roughed up by two husbands who mistake his companions for their wives. Then on to Switzerland and a forced landing near a wedding festival; to Cairo, where Jerry is abducted and found by Marian in a harem; and back to New York.
