改编自同名戏剧的BBC2台电视电影，这部“未来历史剧”讲述伊丽莎白二世逝世后，查尔斯终于继位成为国王查理三世，但却因为拒签有争议的法案而引发政治混乱和局势动荡，而王室和政客此时都各怀鬼胎和野心。
The multi-award-winning, internationally successful ‘future history’ play is to be adapted by award-winning playwright and television screenwriter Mike Bartlett (Doctor Foster) from his own Olivier Award-winning script. Fellow Olivier Award-winner Rupert Goold will direct, reuniting the creative team behind the play originally produced by the Almeida Theatre. The piece, daringly written in blank verse, sees Prince Charles ascend to the throne following the Queen’s death. But when he refuses to sign a controversial bill into law, political chaos ensues – a constitutional crisis, rioting on the streets, and a tank in front of Buckingham Palace. Charles, meanwhile, is forced to wrestle with his own identity and purpose as a ceremonial monarch.
