Well it's all about a hockey player who thinks he's great at playing hockey, but he's actually kinda bad at it, so he never really makes it to any proper games- which results in his really bad temper lol. So anyway his grandma is in really bad debt so she has to live in this awful retirement home, with the manager threatening her if she tells her son, Happy, that the home is bad. So Happy then becomes a golf player to buy his grandma's house back, but he has to lay against a golf legend, Shooter Mcgavin (who's really annoying). During the film he fights crocodiles, loses his friend/trainer, creates poems (anyone who's watched it will know what I mean XP) and even fights Bob Barker

but the film is really funny. Here's a link fir more info:
