I didn't get it. It was a film I saw as a teenager and I remember how bad it was.
It seems that everyone was enjoying an hedonistic lifestyle, the upshot being, however, that you ended up dying because of it.
My lasting memory is of Richard Todd (what was he thinking) walking quite happily to the firing squad, just to impress the girl.
Plan 9 from outer space might be a bad film, but this is so much worse. This will never have the cult following of Plan 9 and I hope, in a perverse sort of way, that this film gets deleted and is never seen again.
