A quartet of sexy ladies (from Sweden, Denmark, China and Germany) travel to London to work as au pairs and end up in various saucy situations involving a great deal of gratuitous clothes-shedding. That's all there is to it really.
On the plus side the ladies are very attractive and look good with or without their togs on - especially the beautiful and shapely Gabrielle Drake (who also starred in UFO and Crossroads). Just think though, they are probably all drawing their pension nowadays.
The film's director Val Guest made his name in the field of sci-fi and horror and his directing credits include 'The Quatermass Experiment', 'Quatermass 2', 'The Abominable Snowman' and 'The Day The Earth Caught Fire'. In the 1970s, as well as directing 'Au Pair Girls', he also directed 'Confessions Of A Window Cleaner' so his career definitely headed in a more lewd and crude direction.
If you are a fan of the 'Confessions' films or some of the bawdier 'Carry Ons' then you will probably enjoy this movie.
