- Plot: An urbane, sharp-tongued expert on how to stay young interrupts a lecturing tour to prove his theory at a dilapidated old people's home. To the despair of his agent and the alarm of the priest running it, he infiltrates the home by lying about his age and sets about lifting the occupants' spirits and making them feel young again.
