A hard to find horror/crime thriller from Spanish horror legend Paul Naschy and directed by Jos Luis Madrid. Set in a snowy Berlin where a black gloved killer is murdering young couples. The killer films his own deeds and sends the evidence to the police. Vera (Patricia Loran) takes interest in the case and starts her own investigation with the help of her antique-dealing boyfriend Boris (Paul Naschy). During a stake-out in a park the killer attacks them but doesnt kill them. Instead he drugs them and leaves a message – he will kill them one by one when they least expect it! This is a fair quality print in Spanish with English subs.
