1895. The British colonisation of Indian continues despite the threat posed by the Khasi of Kalabar and his loyal army of Burpers. Rebellion seems imminent when it is discovered that the feared 3rd Foot in Mouth Regiment (The Devils in Skirts) actually wear underwear under their kilts. When the Khasi receives proof of this he starts an uprising among Bungdit Din's Burgers against the British forces under Sir Sidney Ruff-Diamond. However Captain Keene leads a small group of men deep into Indian in an attempt to stop the approaching massacre.
If you hate the Carry On films with a passion then chances are you will hate this one as well. However for fans or those who enjoy the sense of humour when it works, then it is likely that you will love this film as it is one of the best of the series. The plot is very un-PC by today's standards (imagine having so many white actors playing Indians today?) but this isn't really important here. The plot is actually quite well developed for a carry on film and acts as a suitable framework for the jokes, allowing it to feel like a film rather than just a series of sketches and innuendo held together by the thinnest of threads.
The plot certainly helps but it is the strength of the script that makes this such an enjoyable film (if you can call a script full of innuendo `strong'). The film has so many really enjoyable lines that it is impossible to list them all; of course, if you don't like their breed of innuendo then you shan't like this but I do and this is as good and as honed as they got it. Lines such as `rank stupidity', `Fakir. Off', `and up yours' and `I wouldn't trust him an inch' are all well scripted and display a higher class of innuendo (if you know what I mean): even character names are good if not subtle; Ginger Hale, Bungdit Din, Jelhi, Busti and Khasi to name a few. It helps of course that the cast are so talented at this type of comedy and deliver their lines with perfect timing and perfect facial expressions and reactions. James and Williams lead the cast and are easily the best two in the whole film - they have the best lines, the best reactions and the best timing. The rest of the Carry On regulars are all very assured and delivered the material with the ability of pro's; Hawtrey, Scott, Sims, Bresslaw, Butterworth and Douglas are all very good and it is true that this is almost a who's who of British comedy of the time. Roy Castle is good but he is very much a straightman in the piece.
Overall, this is the film that those new to the Carry On series should seek out as it is one of the films where they had the best material (plot and script) as well as a full cast of very talented British comedians. It is still based on innuendo and silly gags but it is funny and enjoyable.
