PRIMEVAL'S CAST OF CREATURES ALL RETURN FOR A DEVASTATING SEASON FINALE

***MAJOR SPOILER ALERT***

The season finale of BBC AMERICA's hit thriller, Primeval, will prove deadly for more than one member of the team. Since unexplained anomalies began ripping holes in the fabric of time, Professor Nick Cutter (Douglas Henshall) and his team have faced off against everything from a sabre-toothed tiger to a family of raptors to deadly predators from the future. Now a lethal experiment may unleash all of these creatures at once, threatening to destroy the human race. Primeval season finale airs Saturday, November 1, 9:00 p.m. ET/PT

In the season finale of the hit adventure series from the creator of Walking With Dinosaurs, tension has hit an all-time high. Cutter, Jenny (Lucy Brown), Connor (Andrew-Lee Potts) and Abby (Hannah Spearritt) are all being held captive in an abandoned Ministry of Defense base � surrounded by deadly creatures that all look too familiar. While Cutter is reeling from the revelation that his wife Helen (Juliet Aubrey) helped government lackey turned traitor, Oliver Leek (Karl Theobald), capture creatures from anomalies, he learns of Leek's plan to breed predators for an army of beasts. This will make Leek the most powerful man in a new and troubled world.

As Stephen (James Murray), who is under the influence of Helen, faces off against a Silurian scorpion at a busy beach resort and Leek's threat of creatures being released across Britain looms � it is clear this day will not end without tragedy. Is there anyone the team can trust? Will anyone be able to save them and could they all make it out alive? What hope exists for the world outside?

Before the season finale, the Primeval team faces mer-creatures from the future lurking in the canal, Stephen and Cutter are caught in the Silurian desert and Lester's worst nightmare is realized as a mammoth rips through traffic on a London freeway.
