An archeologist in India kills a sacred monkey in a temple whilst drunk and is cursed by the priest. Years later he invites the surviving investors in his expedition to stay at his remote country house, where people start dying and a mysterious ape appears to be behind them. This is a variation on the murder in the isolated mansion theme with secret passages and apes roaming the house. This is not the best version of the theme, but not the worst either.
