The name of the OVA is also the name of the ship that serves as both the home and the interstellar headquarters for an all-female band of notorious pirates.

Thanks to a stowaway who hides himself aboard their ship following one of their raids, they learn of the ultimate treasure: the Gnosis (pronounced "G'Nohsis" in dialogue), an artifact reputedly from old Earth itself.

Armed with a little luck, a sniper gun that can shoot from orbit, and a technologically advanced ship, the crew of the Sol Bianca are about to make a run for the greatest prize of all.

This has been a reason stated by Matt Greenfield at numerous anime convention industry panels as to why a DVD release has never occurred.

A single video game was released based on the series for the PC Engine CD-ROM² on June 29, 1990[2] by Nihon Computer System exclusively in Japan.
