Fort Worth lawyer Ben Carpenter is facing an almost unwinnable case against a powerful Dallas businessman. It could shatter Ben's career.

Now armed with booze and litle green pills, the party sets off for the border. What Ben doesn't know is that he is heading straight for a strange confrontation--with his opponent.
