He is invited down to the country house where Laura lives with other family members (who are all odd in their own ways). Bob suspects he knows who the blackmailer is though it is quite obvious he is being manipulated by Laura, unfortunately for Bob he gets endlessly distracted by bored housewives and ends up in various uncompromising positions...
A confused film though not unentertaining. It is a saucy sex comedy though the sex is pretty tame and barely erotic (though the film has plenty of nudity) and the comedy is sometimes suspect and often falls flat. It is all very politically incorrect nowadays of course though that is no bad thing. It certainly has plenty of stars in it including Diana Dors, Harry H Corbett, Ian Lavender and Adrienne Posta. Probably the best part of the film is when Bob goes to a police station and he passes Police 5's Shaw Taylor!
