The plan was as follows; Naramaro and others would rise an army to kill Nakamaro and relieve the Crown Prince of his position, then deprive ekirei (a bell needed for the exercise of imperial power) and Imperial Seal, enact the decree under udaijin (minister of the right) FUJIWARA no Toyonari, relieve the Emperor of his position and enthrone a new emperor among Prince Shioyaki, Prince Funado, Prince Asukabe and Prince Kibumi.
計画は、奈良麻呂らが兵を起こして仲麻呂を殺して皇太子を退け、次いで駅鈴と玉璽（ぎょくじ）を奪い、右大臣・藤原豊成を奉じて天下に号令し、天皇を廃して塩焼王、道祖王、安宿王、黄文王の中から天皇を推戴するというものであった。
