L'Armée secrète du tyran

With both of his main henchmen killed by Vegeta, Frieza summons his elite fighting squad, the Ginyu Force. Meanwhile, Gohan finds the Dragon Ball Vegeta hid underwater, and heads back to the cave with it. However, he notices Vegeta on his way back and drops to the ground, hiding until Vegeta threatens to blow the surrounding area to pieces. Gohan reveals himself and is able to keep Vegeta from realizing that the last dragon ball is hiding right behind him. Amazed at his luck, Gohan brings the Dragon Ball back to Krillin and Bulma. He and Krillin then take off toward Guru's place, leaving the Dragon Ball in Bulma's possession. They hope that Guru will awaken Gohan's hidden power. Vegeta returns to the village and discovers his dragon ball is missing and realizes that Gohan had taken it (also he draws a conclusion about the dragon radar), furious he returns to the cave but was too late as Gohan, Krillin and Bulma had already left.
