The story of Amelia Conway, a highly successful divorce attorney in San Francisco who has insisted on using her maiden name while married for 15 years to a highly successful construction engineer. He never forgets anniversaries, birthdays and holidays, but his roving work and roving eye keep his side of their double bed more unoccupied than occupied. 

Amelia has never dreamed her marriage might become endangered, although she's been aware of her husband's casual affairs, until his new over sexed blonde secretary asks her to arrange an annulment so she can marry a married man. He is, of course, the motel happy engineer.

Shall she give up the man she loves and simultaneously clip him of their community property as punishment for his philandering, or should she try to save the marriage by turning to a psychiatrist with a nervous tic and a yen for the blonde who turns men on faster than she can type? Amelia finds the answer two hours and two hundred laughs later with the aid of a tape recorder and her young Machiavellian associate who is short in height but long in ideas.
