Outside an administration building, assemblers demand clone rights. Giant robot cops arrive and tell the assemblers to disband or they will start shooting. Entering the fray is Jennie, a Civil Investigator, down on her luck and almost broke. Hired to take out the speaker during the assembly, Jennie winds up in jail.
Captain Beesley, a man with a glass eyeball, springs her out - he has a job for her: stopping the Banshees, what are thought to be scientists from outer space that can live in human bodies.
Come join Jennie (aka Guts), and her partner Blood, an emancipated clone, as they begin to sniff out Banshees.
