It's Eddie who finally gets Frankie to take Maggie on and she turns out to be a really good boxer. We see a number of contests and she moves up. During this time, she buys her mom a house and goes back to Texas with Frankie to give it to her. Her mom laughes at her -- says she can't take it because she'd lose her welfare (*not necessarily -- MJL*) -- and says she should just get married and have kids (*that worked so well for her -- MJL*).
Maggie gets to the point where she's playing for the welterweight championship and the existing champion hits her illegally several times and gets fined, but the last time she's made Maggie's head hit the rails and Maggie becomes paralyzed from the neck down. She still gets her share of the money, but Frankie feels guilty and is almost certainly contributing, too.

There are other things she says "no" to and her life changes.
