 A childless couple (Kinnear & Holly) attempting to conceive discover that his sperm are "lazy". Several trips to a fertility clinic prove fruitless. Also, the wife had surreptitiously quit taking the pill and provided her doctor with a sperm sample before the husband agreed to start trying to have a baby. The deception alienates the husband for a time. To compound things, a female architect has the hots for the husband and lures him out of town on business at exactly the wrong time.
