In 1975, an unpopular Japanese punk band called "Gekirin" (Wrath) starts work on their third album. Unfortunately the band is a little ahead of its time; punk won't be marketable until the Sex Pistols debut in the UK the following year.
Due to nonexistent sales, their record company decides to drop them and they break up soon after recording their final song: "Fish Story". In 2012 a huge comet can be seen in the sky on a path to destroy Earth. The U.S. has failed in their attempt to blow it up and with only five hours left before impact, all major city streets are completely abandoned.
That is, except for one record store that continues business as usual. Within the store, "Fish Story" can be heard playing on an old turntable.
