The Triangle:

Scientist Seth Brundle (Jeff Goldblum), journalist Veronica Quaife (Geena Davis) and her editor – and ex – Stathis Borans (John Getz).

Does It Get Complicated?  

Ordinarily, arrogant jerk Borans wouldn’t stand a chance of getting kooky Veronica back – bug-eyed Brundle is perfect for her.

But Brundle’s not feeling himself these days, and when he is, body parts are coming off in his hands.  Not even Borans is that repulsive.

...At least, until Brundle decides to level the playing field by giving his rival an insectoid kiss full of hand and leg-melting corrosive enzyme.
