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. Win Win - IMDb Win Win - Yahoo Win Win - Yahoo Blog
