Primeval: Series 1-5

The complete seasons 1-5 of the dinosaur adventure series starring Douglas Henshall as evolutionary zoologist Nick Cutter, who discovers prehistoric creatures alive and well in the present day.

Needless to say, the natural world is turned on its head and humanity faces a threat to its very existence.

Unexplained anomalies are ripping holes in the fabric of time, allowing creatures from the very earliest stages of Earth's development to roam the modern world, and Cutter and his team struggle to keep the looming disaster secret while dealing with savage dinosaurs and other deadly foes.

Cutter also has to deal with a deeply personal dilemma - he discovers that his wife Helen (Juliet Aubrey), missing believed dead for eight years, has actually been travelling in the past.

Now she is back with possible answers to the riddle of the anomalies - but is it an answer she is willing to share?
