The Butterfly Theory - the phenomenon whereby a small change at one place in a complex system can have significant effects elsewhere. A thriller oscillating between three generations... In 1937 Amy's life was consumed by trying to survive, living hand to mouth on a small farmstead in the wild wind-swept hills of the Derbyshire moors high above the village of Castleton, England. Never knowing where the next meal might come from and with the added burden of caring for her aged, alcoholic father, Amy's concerns cannot afford to stray far from the confines of High Oakham Cottage. Out of the blue, a new bright, fresh horizon opens before them in the form of a circus. Amy and her father, being swept away by the arrival of Circus Franconi, are transported by the kaleidoscope of fascination, colour and energy that the circus presents. As the ringmaster traverses his audience with an exciting realm of chaos, surrealism and magic, his long-awaited fantastic finale is yet to be unveiled. Waiting in the wings to explode in a confetti concoction of perfidy and intrigue embroiled in a dark long-forgotten past, the sadistic influence of the ringmaster creeps silently through the very walls of High Oakham Cottage, searching for the best finale ever. As the saying goes, the show must go on...and on...and on... In 2020 a father and daughter, Len and Georgia, move to High Oakham cottage to escape the chaos of London following the tragic death of Len's wife. Their lives turn for the worse when they find themselves embroiled in a mystery that has haunted the locals for years.
