In an old castle there are three ghosts who, after scaring everyone, are left alone, bored to death and don't know how to pass the time. After a few minutes of discussion they decide to play a prank on the ghostbuster Roberta Farnese, (who doesn't catch ghosts but cocks) and they call her asking her to come to them urgently pretending to be scared humans. After a while Roberta Farnese the CockBuster arrives and with her equipment begins to look for ghosts to chase away. After some research she finds them and begins to engage in a fight with them to the last... dress. In a flash one of the ghosts makes her work overalls disappear and she is left with a breathtaking dress, but she with a reversal of flow transforms the ghosts back in a flash into living flesh, at that point she will know how to defeat them and send them back to the afterlife.
