The Curse of the Jade Scorpion

Allen stars as C.W. Briggs, a set-in-his-ways old-time insurance investigator who refuses to get along with the bright new efficiency expert, Betty Ann Fitzgerald (Helen Hunt), brought in to streamline his office's operations. When a magician, played by David Ogden Stiers, hypnotizes them as part of his stage act, Briggs unknowingly becomes a jewel thief while falling in and out of love with the exceedingly more confused Fitz, who is carrying on a secret affair with the married head of the company (Dan Aykroyd). Mayhem ensues as a pair of brother detectives zero in on the criminal, a sexy debutante comes on to Briggs, and Briggs and Fitz start suspecting each other. (official distributor synopsis)
