Movie about fights in school/college/parties.

Greetings,

Well I didn't saw the movie but I saw the trailer some time ago and I can't remember the name. It's about how a guy moves to a new school/college and goes to a party and there is some kind of fight club where he gets beaten, he wants to revenge so he starts practicing. That's all so far. Thanks indeed for help.

Never Back Down (2008)

Plot Synopsis: At his new high school, a rebellious teen is lured into an underground fight club, where he finds a mentor in a mixed martial arts veteran.
