Nick Freeman is a motorcycle racer who, following the death of his brother, inherits a revolutionary prototype motorcycle, and is determined to race it at the British Grand Prix at Silverstone.

When one of Regan's snouts complains that his girlfriend's recent suicide was murder, the flying squad detective feels compelled to investigate. He uncovers a conspiracy that reaches the heart of the government, and finds himself fitted up, suspended and under the scrutiny of Special Branch.

Henry Jekyll is a troubled man. His wife died of pneumonia. He wants his sister-in-law, but her father forbids any contact. And his experiments into the dual nature of man have yielded a personality-splitting drug that he has tested on himself, changing him into an uninhibited brute who seeks violent and undignified pleasures. Jekyll quickly becomes addicted to the sordid freedom induced by the drug. He can commit the most enjoyably revolting deeds, then return to his laboratory and use an antidote to change back to his original form, so that his lofty persona remains untarnished.

In the early 19th century, Dr. Frankenstein discovers the secret of life – how to create a perfect man – powerful, intelligent and immune to disease. But something goes wrong in the laboratory and the doctor’s hideous creation disappears into the night. At first, Frankenstein hoped that the horrible monster would perish in the wilderness, but now he senses that it’s alive and sets out for him. Dr. Frankenstein tracks the creature to the Arctic, where the two must battle to decide who will become the master of the other’s life…or death.
