Set in Mueang Phayao, Invalid Throne examines the land and people who used to own property in the province. The disputed areas were overtaken by new feudalism and turned into a gold mine and an exclusive monastery, allowing only a select, elite few to enter its landscape. Shot on location in northern Thailand and in a studio (using a miniature landscape), the film weaves historical narrative with the personal memories of Kamjorn Sankwan, the artist and protagonist who was raised in that area, thereby raising questions to what constitutes as a national, collective history.
