Trouble precedes Ardis Cole to the site of a Han Dynasty tomb in China. Dr. Yong Po, who has asked for her assistance, is being stalked by a person wearing a crimson opera mask. Ardis is concerned when her co-worker, Grant Merlin, fails to arrive at the project, and his ex-wife, Sheri, takes his place. More problems arise when Sheri is attacked on the cliffs by the same masked intruder. Ardis' search for the tomb of emperor Sun Yan leads to ancient intrigue surrounding a captive princess, referred to in his poetry as the "Lady of White Jade." As Ardis delves deeper into the tomb's secret, a centuries old crime of passion is eerily replayed in the present.
