Fred Astaire plays a man on the skids. Normally spry Astaire is cast as Joe Quinlan, an ailing and broke pool player, who arrives in town for a tournament. At Blair Hospital for a check-up he is reunited with his estranged daughter, Sister Benjamin (Laura Devon), a medical missionary. Just returned from overseas, she too is a patient. Father and daughter are sceptical of each other's routine check-up explanation. Kildare (Richard Chamberlain) is caught up in the middle of a probe for truth.
