Could someone plz tell me the story line of Dragon Ball Z Kai b/c i just start watching it in...like July?

dragon ball z kai has many enimies like majhhin buu that force enemies in teams like goku and piccolo but goku meats more than just sayains like the anadroids and freiza but along the way goku becomes a super saiyan the most powerful warrior in the universe and fights other super sayians like broly,vegeta,and trains with his super saiyan family like gohan,and goten and vegeta his arch nemesis trains with trunks his son whoes also a super saiyan. END.

bastikly its about an alien sain boy that was sent by his kind to destruoy the plant and all life on it but he was found by and old coot named gohon when he meet this boy hes orignal name was
chakerot but gohon named him goku and he had a tail that at a full moon he turend into a grate HUGE ape it was a chemeckl reachon of a saien but latter on he had his tail removed but a man from a difrent race and planet he was still vilont but he hit his head and became earths prottecter latter he married a girl and had a son they named him after gokus founder and name him gohon and you will figer out the rest

o yah sure well vegeta and nappa landed on planet earth and attacked the z fighters(goku,piccolo,gohan,tien,yamcha,and krillan)goku of course goku won easily.then krillan bullma and gohan went to planet namek but then vegeta went htere too.to look for the dragon balls.and so did frezia. goku fially recoverd and fought frezia and in the middle of that goku bacame a super sayin and won the battle then future trunks came and warned the z fighters about the androids and then he left goku arriv ed on planet earth and so did gohan krillan and bullma. but to turn things around the androids that were going to be there (androids #17&18)wernt dr.gero were there and he was part android to but now he is trying to run and activate androd 17 and 18. that is it for now.
