Four psychic teenagers—Mia Alice, Roll Kran, Lamba Nom and Pai Thunder—are brainwashed by the scientist Dr. Tarsan as pilots of his greatest experiment—the giant robot Dangaioh. But as their memories slowly return, these pilots use their abilities and Dangaioh to combat the tyranny of Captain Galimos and the Bunker Space Pirates.

Movie based on the 1985 TV anime with an original plot.

The story is set in December of 2199, when the streets are full of anticipation for the end of the year and the start of the new one. Amid the celebrations, word spreads that Ragna the Bloodedge, an SS-class rebel with the highest ever bounty on his head, has appeared in the 13th Hierarchical City of Kagutsuchi. The apparent aim of Ragna or the "Grim Reaper" is the destruction of the system controlling the world. To collect the bounty, a motley array of unrivaled fighters converge on Kagutsuchi.
