Dragon Ball Z - Season 1

With no new battles to fight, Goku has been living a quiet life in the countryside with his wife Chi-chi and their son Gohan! While Goku makes plans to spend a happy day with friends on Master Roshi's island, a powerful new threat is on its way to Earth. And the arrival of this sinister alien could spell disaster for Goku and his friends! 

Goku and Gohan attend a reunion on Master Roshi's island, where Goku introduces his son to all of his old friends. The smiles quickly fade, however, as an unexpected visitor lands on the island, and for Goku the day becomes a reunion of a different kind. A powerful alien has arrived. It's Raditz, Goku's evil older brother! 

Raditz has kidnapped Gohan! And unless Goku agrees to forsake his friends and the people of Earth by joining the sinister Saiyan, he may never see his son again! All hope is not lost, however, as a second uninvited guest arrives on the island and Goku forges an unlikely alliance! 

The situation looks bleak for Goku and Piccolo, as Raditz easily deflects every attack they send his way. But Piccolo may have a way to stop the sinister Saiyan. He's perfected a powerful new attack... the Special Beam Cannon! There's only one problem. Piccolo needs time to gather the energy for the blast, which means Goku will have to last for five minutes against Raditz alone! 

As Goku takes blow after punishing blow from the evil Raditz, Gohan is able to watch no longer! The young boy's rage unlocks an awesome power sleeping within him, and he unleashes a mighty attack that not even Radtiz can resist! But as quickly as Gohan's power appears, it vanishes. And when Raditz prepares to strike back, Goku must make the ultimate sacrifice to save his son! 

With Raditz defeated and Goku gone from this world, the surviving Z-Fighters must begin preparing for the arrival of two more Saiyans who will reach Earth in one year's time. Piccolo takes Gohan into the wild for a severe training program, in the hope that his hidden power will be revealed. Meanwhile, Goku embarks on a new adventure in the next world, as he must travel the endless miles of Snake Way to receive training from the legendary King Kai! 

Gohan begins his first day of Piccolo's training. Alone in the wilderness, he must quickly learn to take care of himself. But that isn't easy when he's tired, hungry -- and being chased by hungry dinosaurs! If Gohan's first day is this dangerous, how will he ever survive for the second? 

Krillin receives a startling message. Korin wants him to gather Yamcha, Tien, and Chiaotzu and report for special training! And if that weren't enough, he and Roshi still have to find a way to tell Chichi what's happened to Goku and her son. Meanwhile, Gohan's training causes him to undergo a shocking transformation!
