VERY strange British offering from 1970.
The story is set in swinging London of the late 60s & concerns two odd twins who arrive as "babes in the woods" & are quickly adopted by a fast, wealthy set of bored, drunken & drugged-out aristos.
Only are they quite as innocent as they appear?
As new bonds start to form amongst the group & threaten to destabilise the unnatural relationship between brother & sister the mood shifts from one of careless gaiety to one of ominous foreboding.
Terrible things are bound to happen....&, indeed, they do.
Jolly good, but awfully strange.
I think it is based on a book, but would have to re-watch my video to find the title as it is not listed in any of my film guides.
I note that this is the only R/V, so it obviously must be hard to get hold of.
