Ataru and Lum must replay their fateful game of tag to decide the fate of Earth, that's being threatened by giant space mushrooms, as well as their relationship.
This movie was based on the final chapters in the UY manga series.
Even if it takes a lifetime, I'll make you say it.
Ataru: I'll say it on my deathbed!
During the closing credits, Kôichi Kitamura is listed as being the voice of Upa (Rupa's great-grandfather). This is incorrect, Upa's voice was in fact performed by Ken'ichi Ogata, who also provided the voice for Ataru's father. Kitamura's actual role was that of Lum's great-grandfather.
The end credits show a picture of Tomobiki while scenes from the movie are shown on the left side of the screen.
