Plot
The movie features the villain Garlic Jr., who seeks revenge for his father who wanted to become Guardian of Earth and himself wants to become ruler of the Earth. In order to have his wish fulfilled, his servants kidnap Goku's son Gohan to get the Dragon Ball he is carrying. Garlic Jr. then summons Shenron using the Dragon Balls and wishes for eternal life. Goku must combine forces with his archrival Piccolo Jr. in order to save the world. With Piccolo, and Kuririn's help. Goku is able to defeat Garlic Jr.'s evil servants and rescue Gohan.

Kami arrives and confronts him. However, he is unable to defeat him, and in a last ditch effort Kami decides to sacrifice himself to kill Garlic Jr. However, Piccolo and Goku arrive in time to take on Garlic Jr. When they seemingly defeat Garlic Jr., Piccolo wants a rematch with Goku. However, the immortal Garlic Jr. emerges again & opens a Dead Zone portal in order to trap everyone within.

With time running out, and with moments away from being sucked into oblivion, Gohan's hidden power appears, and he sends Garlic Jr. into the portal, trapping him inside, and saving everyone. Remarkably, in the end of it all, Gohan doesn't remember a thing of what happened, instead believing that his father defeated Garlic Jr., and with amazement, Goku figures his son is no ordinary boy, but one with a great hidden potential. Goku remarks that he'll tell Chi-Chi about Gohan's hidden power when Gohan is older. At the end of the film, Piccolo is seen from above, looking down on Goku and his friends and vows that one day, he will defeat Goku.

Trivia
all information on Dragon Ball Z movie 1 came from http://dragonball.wikia.com/wiki/Dragon_Ball_Z:_Dead_Zone
 * Flashbacks in the Dragon Ball Z episodes "The Heavens Tremble", "Black Fog of Terror" and "Fight with Piccolo" feature animated footage from Dead Zone.
 * This is the only movie to feature the ending theme song from the TV series ("Detekoi Tobikiri Zenkai Power!"). All other movies feature original songs as the ending themes. However, the animated sequence at the end is slightly different from the one in the series: this is just Gohan running around on the planet, and features none of the "cutaway" scenes from the series (Yajirobe with Kami, the 23rd World Martial Arts Tournament, etc.). Gohan dressed as the Monkey King at the end is still there, though.
 * This is one of the only post Dragon Ball entries in the series where Goku uses the Power Pole in combat, along with The World's Strongest.
 * Despite being released under the Ultimate Uncut Special Edition line, the FUNimation version is actually more edited than the original Pioneer Entertainment release.
 * While the movie itself was fully uncut, the Special Edition version used the wrong opening animation. This was corrected in the double feature release.
 * This is the only version ever to be shown in 4:3, in both the United States and Japan. Every other release, including Japanese releases were cropped to 16:9
 * In the Remastered Uncut edition of this movie, the insert song was replaced in the English audio while in earlier FUNimation releases of this movie had kept it in. This also goes for The World's Strongest which also had its insert song replaced in the remastered uncut English dub. Though if using the audio for English with Japanese score, then the songs are there.
 * Garlic Jr. and cronies try to kill Piccolo, and know that doing so will kill Kami as well, but they do not seem to know that killing them will cause the Dragon Balls (which Garlic Jr. needs to be immortal) to vanish.
 * There are a few discrepancies. For example, Krillin was introduced to Gohan in the movie, yet he did not know who he was in the beginning of Dragon Ball Z. Additionally, in "Unlikely Alliance" ("The World's Strongest Team" in the original English version), Goku comments on his discovery that Piccolo trains with weighted clothes; however, he makes the same comments in Dead Zone.
