An outrageous collection of surreal, short attention span non-sequiturs largely revolving around Guitar Brother, his randy older sibling, and the pair's portly Caucasian brother.

The most dangerous and exciting car race in the universe is held only once every five years. And that's tonight. The competitors are lined up at the starting block. In his vehicle, JP, the most daredevil driver on the circuit, is ready for the green light. Female driver Sonoshee, with whom he is secretly in love, is also on the starting line. She will stop at nothing to get on to that podium. In this race, not only is anything possible, but also anything is allowed. In fact, their adversaries have modified their vehicles to equip them with highly destructive weapons; with such participants, it is hardly surprising that Redline is forbidden by the authorities, who will try anything to halt the proceedings.

A spell of time in the life of a family in rural Tochigi prefecture. Yoshiko is not an ordinary housewife, instead working on an animated film project. Uncle Ayano, a successful music producer, is looking to get his head together after living in Tokyo. Meanwhile, Sachiko is concerned with why she seems to be followed by a giant version of herself. As the lazy days pass by, each member of the family is followed in a series of episodic vignettes.

In dreamlike mountain scenery, Toshiko makes a daring escape from her sexually warped Uncle Sonezaki. Fortunately, she met Samehada as she runs for her life, which is also escaping from some slayers. What follows is a wild chase that leads the audience into a comically violent world.
