Someone is stealing millions in jewels from New York City's upper crust and the only man who can crack the case is completely clueless. Woody Allen stars as CW Briggs, the top insurance investigator in 1940's New York--or so he keeps telling the firm's new efficiency expert, Betty Ann Fitzgerald (Helen Hunt). Briggs prides himself on being able to crack any insurance caper by getting into the mind of the thief. Now, thanks to the hypnotic powers of the Jade Scorpion, the mind of a thief is getting into Briggs.
