Wracked with guilt over her younger sister's suicide, pretty young karate student Megumi accompanies a group of older friends on a camping trip into the woods, where they're attacked by feces covered undead.

Yoshinari Bessho, the feudal lord of Tanba Province, is a collector of butterflies and has his concubines tattooed with butterflies as well. One day while hunting, Yoshinari sees Gennosuke Akizuki's beautiful wife, Okoto. He kidnaps her, tattoos a butterfly on her shoulder and takes her for his own. Feeling shame for what has happened, Okoto throws herself into a well and commits suicide. She then returns as a ruthless ghost that seeks revenge against Yoshinari and his retainers. Whenever the ghost appears, mysterious butterflies always fly around her...

In 1999, advanced science and technology enriched people's lives, but the damage caused when they were misused for crimes or went out of control and went out of control was also great. The Special Rescue Police Winspector (abbreviated as WSP) was established to deal with such a situation. Their purpose is not only to investigate crimes and arrest suspects but also to save the lives of those involved in crimes and disasters.

After the Winspector police team leaves Japan to fight crime in France, Chief Shunsuke Masaki realizes he must create a new police team to defend Tokyo from crime. He creates Solbrain – a high-tech special rescue force, expert in missions requiring rescue and firepower. Its leader is Daiki Nishio, a rookie detective who can use the Plus Up command in his car to transform into SolBraver. Other members are Reiko Higuchi, also able to use the Plus Up command to transform into SolJeanne, SolBraver's female counterpart; and SolDozer, a yellow bulldozer robot.
