Wij Alexander (TV series)

We Alexander is based on the story of the third son of King William III and Sophie of Württemberg. According to the history books, this Alexander had a short life: from 1851 to 1884. The amazement of psychiatry student Jan Giltay is therefore great when, in 1909, he meets a certain patient number 4 in a clinic who claims to be Prince Alexander. Indeed, the man knows a remarkable amount about life at Court. There are also increasing indications from other quarters that this could very well be the 'forgotten' crown prince. Patient number 4 is said to have a mysterious box - with information that could shake the entire royal family to its foundations. - IMDb
