Sidney Pink directs this 1960s horror starring Bent Mejding and Asbjorn Andersen. When copper miners uncover the frozen tail of a prehistoric creature in Lapland they bring it to an aquarium in Copenhagen, Denmark, headed by Professor Otto Martens (Andersen). After a negligent scientist accidentally thaws out the frozen tail, it quickly becomes apparent that it has the ability to regenerate. Soon the 'Reptilicus' is fully formed and goes on a tyrannical rampage through the Danish countryside before setting its sights on destroying Copenhagen.
