This obscure Italian crime potboiler features a nominal performance from a slumming Boris Karloff as wealthy businessman Don Gaetano, who assists a narcotics detective (Franca Marzi) in rescuing his kidnapped daughter from a drug-smuggling ring based on the island of Ischia. The syndicate's leader is using the girl as a shield to prevent the inspector from getting too close to their operation. Predictable plot twists abound until Gaetano is revealed as the man who masterminded the abduction from the beginning. Karloff, still in a pre-Thriller career lull, would fare considerably better in his next Italian production, I Tre Volti Della Paura, thanks to the deft hand of director Mario Bava. Also known as Monster of the Island. ~ Cavett Binion, Rovi
