Karate Genius

Tyler thinks he is just a normal guy who is not good at karate. Until, one day he gets hurt at karate and passes out by another karate partner. When he wakes up he doesn't know it but, he is in the year when karate was invented. He must then learn about karate and all the right moves and then go back to his present time and show his friends, family, and his karate master to get out karate. Will it work or will he ever get back to the present?
