British India, 1895. The Burpas are revolting but then again The Devils in Skirts who guard the Khyber Pass are none too charming either! Can Sir Sidney Ruff-Diamond (Sid James) prevent the scheming Khasi of Kalabar (Kenneth Williams) from starting a full-scale rebellion, ending British rule & making his cushy job obsolete? Can he rely on the help of the wayward Brother Belcher (Peter Butterworth), & prevent the secret concerning the 3rd Foot & Mouth Regiment from becoming common knowledge among the natives? All will be revealed in this masterly tale of passion, greed & missing underpants set in the raging days of the Raj.
