This one is a must see for you Z Warriors out there... a clean, 85-second look at what to expect from the March 2013 return of Dragon Ball Z anime to the big screen.
Manga artist Akira Toriyama has promised significant involvement in the production, which hits Japanese theaters March 30, 2013.
The story will take place between Dragon Ball manga chapters 517 and 518, in the 10-year timeskip after Goku defeats Buu, before the 28th World Martial Arts Tournament.
From Saiyan Island's translation of the synopsis:
The story takes place a few years after the fierce battle with Majin Buu. Bils, the God of Destruction who maintains the balance of the universe, awakens from a long slumber. Hearing rumors that a Saiyan defeated Frieza, Bils goes on a search to track down the warrior who championed this feat – Goku. King Kai advises Goku to avoid a confrontation, however, Goku is ecstatic that a new opponent has appeared after many years and decides to fight. Unfortunately, Goku is no match for Bils’ overwhelming power and is defeated. Bils leaves, asking if “there is anybody on Earth more worthy to destroy?” Will Goku and the Z Warriors really be able to stop the God of Destruction?!
