Miss Laid Lovers

Miss Laid Lovers (1978) is a mystery directed by Bob Vosse rated 10.0/10.

On a large yacht, skullduggery is afoot, presumably some sort of drug smuggling involving Richard (Ric Lutze) and a mysterious boss/gangster character. On dry land there's plenty of humping (including the inevitable orgy) and searching for information, but no imparting of the latter.
