You are daniel larusso. You won two karate tournaments 35 years ago and also fought someone to the death once (you both survived so it’s fine) and then lived out a normal life. Your high school bully and first (but not last) karate rival reopens the dojo that terrorized you which reignites your passion for karate. You start training a protege of your own and it turns out he’s the son of your first karate rival. It turns out that your first karate rival is now teaching with his sensei, a man that spearheaded an elaborate plot to torture you when you were teenager at the second karate tournament because of your victory in the first tournament. You go back to Okinawa, where you had your first (but not last) fight to the death, where your ex-girlfriend encourages you to reconcile with your second karate rival who was the one you fought to the death and who tried to kill you both. You reconcile with your second karate rival. You go back home. Your first karate rival has had his dojo stolen from him by his insane sensei and his students launch an attack on your home. A small boy is thrown through your window. You have a fight to the death with the insane sensei that ends in a draw. He comes back with the second person who was involved with the elaborate plan to torture you when you were a teenager, the boss karate rival. You find out he has an insane bond villain plan to take over the world with evil karate so you look up your third karate rival, the third person who tortured you when you were a teenager at your second karate tournament. You reconcile with your third karate rival. You reconcile with your first karate rival. On a night out when you’re drinking with with your first and second karate rivals, your third karate rival hijacks your car because he blames you for burning down his business, when it was actually the guy that tortured you. You get kicked out of your own revenge party while your former karate rivals all team to kill the boss karate rival. Both of your children have karate rivals. Your son doesn’t even know karate.
