In Primeval, a team of experts from the Home Office's secret government organization investigates and deals with anomalies – doorways to other times that are allowed to open at any place at any time. Creatures from the past and future enter the present. The team operates from a futuristic-looking base built in an old underground station. The team also has to deal with personality clashes, jealousy, and the ever-present threat of being discovered by the public.
