What is DragonBall Z?
DragonBall Z is the story of Goku, his son, and friends. They go destroy evil with there super natural powers. The first evil dude to come along is Radditz Goku's evil brother. Then Vegeta and Nappa come. Then everyone goes to Namek to get the Dragonballs and run into Frieza. After him everyone goes back to Earth when Mechanical Frieza and King Cold come. This is where Future Trunks comes and he kills Frieza and Frieza's dad. A couple years later (in DBZ time) the androids come. While they're here Cell comes and absorbs them becoming Perfect Cell. Gohan kills him and thats where we are now. Buu will come next. You will be able to look at these sagas in more depth in the saga section (coming soon).
