Plot
A man named Adolf Schwartz, Adolf Hitler in hiding, is living in a Bavarian-style castle in northern California. After an orgy in the dungeon with three women (The Headsperson, The Ethiopian Chef, Limehouse) and a man (Paul) he is murdered when someone places a ravenous piranha fish in his bathtub.
A voluptuous woman named Margo Winchester appears later in the nearby town Miranda and is spotted by local Sheriff Homer Johnson. He tries to make advances but Margo rejects flirtatiously (at this point). After that she is picked up by Leonard Box, a known troublemaker and son of a sawmill owner. An argument breaks out with the result that Leonard subdues and rapes the unconscious Margo, after that she accidentally kills him. This is witnessed by Homer, but he covers up the incident because Box's loaded father would put Margo in jail forever and of course he is horny for the busty beauty. So Margo and Homer wind up sleeping together, starting some kind of relationship, but a mutually unfaithful one as it can be seen later.
