It's not often a nasty divorce can be settled so quickly, that's the position Brad finds himself in, he married blonde Lucille but 2 months in, he started seeing Andrea from his cross fit class. It was true love at first sight, and Brad left Lucille.
Brad isn't smart, and Lucille took the money out of their joint bank account when Brad sent over divorce papers for her to sign. She's not quite ready to sign those papers, and wants to make Brad wait and beg.
Andrea had an idea, she offered to fight Lucille, wrestle her over signing the papers. If Andrea won, Lucille would sign the papers, and give back the money, if Lucille won - she gets the money. Lucille accepted - Brad would be the only one to witness the match, but he had a bad feeling... he knew Lucille was stronger.
Andrea was excited - she knew giving Brad this gift, humiliating his ex-wife would be the top of his lift - but she had no idea what was about to happen.
Part 2 sees Lucille in control, going to finish Andrea in front of Brad, and he can't stop it or else he breaks the promise to stay out of it, and he will never get those papers signed.
