Tess McGill is struggling. She's got "a head for business and a bod for sin," but no one seems to get past the bod. After Tess (Melanie Griffith) quits her latest secretarial job because her co-worker (Oliver Platt) sets her up with an arbitrager (Kevin Spacey) who's looking for a good time rather than a good assistant, she lands at a mergers and acquisitions firm under a female boss, Katherine Parker (Sigourney Weaver). While pretending to be her mentor, Katherine steals an idea Tess suggested, so when the boss breaks her leg on a ski trip and is out of action for a few weeks, Tess takes revenge by pretending she has her boss's job. She even connects with another dealmaker, Jack Trainer (Harrison Ford), who helps her put it together.

My favorite sequence is the one following her night at a reception. The man she drinks with, Jack Trainer, won't tell Tess his name. She tells him she's trying to meet Jack Trainer, who she is scheduled to pitch the next morning. She has a little too much to drink and Jack has to carry her home. She wakes up in his bed, sneaks out, and later manages to pitch the deal to -- the man she drank with the night before! Later, Tess confronts Jack in her (or rather Katherine's) office:

Tess: What did happen, exactly?

Jack: The earth moved. The angels wept. The Polaroids are, are, uh... (gropes in his coat pockets) are in my other coat. (grins) Nothing happened. Nothing happened!
