Returning to St. Petersburg from a Swiss sanatorium, the gentle and naive Prince Myshkin - known as 'the 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. In Prince Myshkin, Dostoyevsky set out to portray the purity of 'a truly beautiful soul' and to explore the perils that innocence and goodness face in a corrupt world.
