Beauty. Brains. Charm. Tess McGill (Melanie Griffith) has them all. In fact, she's got everything going for her except the right haircut, the right clothes, and most importantly, the right job. Ambushed one too many times in her struggle to get out of the Wall Street secretarial pool and onto the management ladder, Tess decides to take matters into her own hands. When her classy, seductive and treacherous boss (Sigourney Weaver) breaks a leg skiing, Tess steps, literally, into her boss's shoes - as well as her apartment, her corner office and her $6,000 dresses. Suitably disguised, Tess forms an alliance with a very capable-and very attractive-Wall Street investment banker (Harrison Ford). Together, they create a deal that could catapult Tess into the big time-or finish her off for good.
