Adventures in Raj era India though this is the Hollywood idea of life back then so don't expect much historical accuracy...
Gunga Ram (Nino Marcel) is an Indian boy (with a very American accent) who works for the Maharaja (Lou Krugman) looking after elephants. A new fire cult dedicated to Sabaka led by a High Priestess (June Foray), who can also control cobras, is causing havoc in his province, burning villagers to force people to worship their new cult. Even Gunga's only sister dies in the flames...
General Pollegar (Boris Karloff) is sceptical about the fire cult and seems to have a problem with Gunga...
This is a pretty basic story mostly involving Gunga Ram seeking to avenge his sister though has plenty of well-known actors parachuted in to perform small roles (painted up to look "Indian" of course). It certainly looks splendid, the Hollywood store of "Exotic India" was extensively plundered for sets, costumes and props. Ample use of stock footage too, usually animals eating other animals. Ultimately though it is a bit of a bore, but frequently so ridiculous as to keep you interested.
