Everyone that has been killed by Frieza and his henchmen on Namek are resurrected, but so far, Guru isn't back yet. Meanwhile, Goku finally decides to use his full power, giving him the edge in his beam struggle with Frieza. Refusing to admit defeat, Frieza breaks off of the attack and blindsides Goku before knocking him deep into the planet and triggering a volcanic eruption, apparently killing Goku. With Goku seemingly beaten by Frieza's attack, Gohan returns to the battle to avenge his father, and to make sure that the cold tyrant dies along with the planet. However, even though Frieza returns to 50% of his full power, he is no match for Frieza. Enraged by Frieza's actions, Gohan powers up again and pounds Frieza, who then decides to use 100% of his full power again. Before Frieza can land the killing blow, however, Guru returns to life, and Goku reappears, and orders Gohan to leave Namek. (Source: Wikipedia)
