Returning to St Petersburg from a Swiss sanatorium, the gentle and naïve epileptic Prince Myshkin - the titular 'idiot' - pays a visit to his distant relative General Yepanchin and proceeds to charm the General, his wife, and his three daughters. But his life is thrown into turmoil when he chances on a photograph of the beautiful Nastasya Filippovna. Utterly infatuated with her, he soon finds himself caught up in a love triangle and drawn into a web of blackmail, betrayal, and finally, murder. Inspired by an image of Christ's suffering Dostoyevsky sought to portray in Prince Myshkin the purity of a 'truly beautiful soul' and explore the perils that innocence and goodness face in a corrupt world.
