Following a short opening sequence in which a henpecked husband finds relief from his wife's nagging by employing the use of a sex doll, the film's presenter tells a quartet of stories concerning adultery and infidelity.

The first concerns Lisa, a flirty miniskirted office secretary, who seduces married fellow office worker Chris The second story involves Liz, a gold-digging model, who becomes involved with a married and rich tennis player, including seducing him in his private jet, and then leaves him when his divorce from his wife Flora leaves him penniless.

Monthly Film Bulletin wrote: "Four tales of adultery, thematically linked by the energy and sexual initiative attributed to Other Women of all ages and sizes.

Any hopes aroused by Richard Wattis' sardonic presentation that Sex and the Other Woman may prove less formulary than rival 'sex surveys' are dashed as soon as the first episode creaks its cumbersomely plotted way to some predictably inexplicit scenes of love-making.

The film makes the usual comic capital out of sexual guilt – hasty copulation on the office couch, speeded-up motion as the characters hurriedly don their clothes after infidelity – while elsewhere script, direction and acting prove equally unconvincing.
