I'm not sure exactly how much wrestling action is involved in the film, but from the trailer it appears that it will play a pretty big role. It looks like it could be a pretty good flick.
Here is a bit of background on the story:
Disheartened attorney Mike Flaherty, who moonlights as a high school wrestling coach, stumbles across a star athlete through some questionable business dealings while trying to support his family. Just as it looks like he will get a double payday, the boy's mother shows up fresh from rehab and flat broke, threatening to derail everything.
I actually got to go to the premier, and talk to the director and actor who played the main wrestler on the movie. It was really good, and the kid was a New Jersey state champ. Realistic wrestling and a good story line. You should check it out when it comes out.
