Enjoyably hammy sub-Hitchcock suspense thriller from 1982 in which Klaus Kinski's plan to kidnap the grandson of a wealthy American explorer is thrown into chaos, placing him and co-conspirators Oliver Reed and Susan George under siege by a black mamba. Kinski is suitably unpleasant, as is the wince-inducing moment when Ollie receives a fatal snake bite where no bloke wants to be bitten.
