Perhaps the best example of Thorne Smith's acutely sharp social humor played out against a backdrop of the Prohibition. Two unrepentant old reprobates are celebrating the 25th anniversary of the seduction which made the stylish old man named Rex Pebble into an adulterer and his companion, Spray Summers into his hard boiled mistress. While their exasperating and highly alcoholic Japanese houseboy, Nokashima, plays ju jitsu with the English language, the two slip into a swimming pool whose waters have been changed into a fountain of youth. Abandoning their clothes and modesty with their advanced years, the newfound youthfulness of their bodies puts into motion an evening of hijinks that only a seasoned and well practiced old couple of sinners could manage to imagine.
