Dragon Ball Z: Dead Zone

Synopsis

During his training on a remote cliff, Piccolo is defeated by a group of unknown assailants. These same attackers then head to Mount Paozu with the goal of stealing Gohan Son's Dragon Ball. Upon arriving, they easily overpower Chi-Chi and Gyumao—Gokuu Son's wife and father-in-law, respectively—and proceed to kidnap Gohan. Sensing something is wrong, Gokuu returns home to find Chi-Chi injured and learns what happened. He goes to Kame House to get the Dragon Radar, which he uses to track the Dragon Balls and locate both the enemies and Gohan.
