本剧是制片人Guillermo del Toro联合梦工厂为Netflix制作的《阿卡迪亚传说》（Tales of Arcadia）三部曲的第二部，也是第一部《巨怪猎人》（Trollhunters）的续篇。故事描述某外星王国突遭邪恶独裁者的占领，一对王室兄妹（一位王子及其尚未结婚的王妃）在保镖的陪伴下逃往地球。他们的飞船在阿卡迪亚橡树镇附近坠毁，来自银河系各个角落的赏金猎人接踵而至。为了掩人耳目，他们决定改头换面混入地球普通人当中，但要想真正融入地球人的生活对他们来说是一项艰巨的任务。与此同时，他们想尽一切办法来维修飞船，以便早日返回母星球驱逐坏人、重建家园。Diego Luna为外星王太子（未来国王）Krel Arikidion配音，Tatiana Maslany为准王妃（未来王后）Aja Arikidion配音，Nick Offerman为他们的保镖Varvatos Vex配音。Krel和Aja在《巨怪猎人》第二季结束前已经现身，他们对Jim、Toby和Claire来说是一对「古怪的新同学」，本剧将把剧情时间倒退回他们刚刚来地球的时候。在这之后，Jim、Toby、Claire和其他《巨怪猎人》角色都将在该剧中亮相，两部剧集的情节也会经常交叉。
