The series follows smart, capable and by the book Grace Narayan (Anjli Mohindra), who was flying high as an inner-city police sergeant before being forced into a 'punishment posting' on the small, antiquated island of St. Jory. Confronted by the forgotten and unsolved case of missing teenage boy Cai, Grace quickly discovers that she must overcome scarce evidence, extraordinary local characters, and the island's strange cult history to uncover the truth.“第二点，就是……这九重天阙的十方天地，实则乃是圣君亲自规范出来；这实在是一项通天彻底的巨大神通；而且……十大天地除了中极天之外，各自有一小块疆域巧妙连接……当然，除掉相对的那两大天地。”
