It seems that our original Karate Warrior, Tony Scott, has moved away from the small coastal town to South Dakota! Who can step into his shoes as the biggest jerk martial-arse champion in the US? No one it seems, which is why his golden kimono and various items are kept in some sort of shrine by best friend/stalker Leo.
It seems that bad guy Dick is still around though, even though inexplicably his name has now changed to Joe. Joe/Dick has not learned any lessons about strutting about the place acting like he's got three balls, so who now is going to stop Joe giving Leo and ass-kicking every two minutes? Enter Larry.
What you'll notice right away about Larry is that he's not an jerk like Tony Scott was. Plus, he doesn't even know anything about karate! Like most of these films, Larry, his sister, and his mother are all at risk from being evicted by an evil landowner, who's niece Larry has just met and fallen for. Larry needs $2500 dollars to save his house, so luckily there is a cycling event taking place, and as luck would have it, the grand prize is $2500! All Larry needs now is some jerks to ruin everything for him.
Larry also agrees to take on Dick in a low-budget karate fight, so obviously not knowing how to practice karate is a bit of an issue there. There are only two possible people in town who can teach Larry how to kick Dick in the dick, so let's present it as a multiple choice question:
1) Is it the fat guy who sells fried chicken, doesn't practice karate, and is the comedy sidekick, or
2) Is it the Japanese guy who has just opened as Japanese restaurant in town, has just kicked three jerk's heads in, and was once the world's top martial art master?
Larry needs a crash course in ass-kicking because he's got three days to learn karate, stop his eviction, win the girl's heart, and get that goddamned $2500? You knows it!
Completely generic in every way a teen sports drama can be, yet filtered through an Italian brain so that you get such important stuff as a Halloween party where Dick comes dressed as Tony Scott, a cycling race that's terrible in every aspect, and bad guys who laugh at everything, the cheese is so thick here the actors practically wade through it. If you liked Karate Warrior 1 and 2, then you'll like this one, because THEY ARE ALL THE EXACT SAME FILM
