John Taylor lives in quiet solitude, designing puzzles for a living, under the nom-de-plume of 'Ludwig'. When his identical twin, James, disappears off the face of the earth, John takes over his brother's identity in a quest to discover his whereabouts.

A dramatic retelling of the life of Ludwig II, King of Bavaria, one of the most fascinating monarchs of modern times. From his accession to the throne at the age of 18 to his passionate support of Richard Wagner and his music. From his ingenuous political commitment to his obsessive construction of extravagant palaces and to his gradual withdrawal into a lonely dream world, an epic narrative of breathtaking grandeur.

故事开始于1864年的德国，年仅19岁的路德维希二世（赫尔穆特·贝格HelmutBerger饰）登上了王位，成为了统治巴伐利亚的国王。实际上，路德维希是一个性格非常优柔寡断的男子，根本就不适合作为国家的统治者，他脆弱的自尊和薄弱的意志力常常将他置于痛苦的境地之中，这种痛苦在他挚爱的表姐伊丽莎白（罗密·施奈德RomySchneider饰）含恨远嫁他乡之后，变得更加的强烈。实际上，路德维希也曾设想过实现自己的政治抱负，然而，他身边聚集着的，是各怀鬼胎的三教九流，当时间来到19世纪下半叶时，他的所有设想都化作了泡影。之后，为了逃避繁琐的政事，路德维希躲进了一座城堡之中，并且最终被大臣视为患有精神疾病，而遭到了废黜。
