In 4 BCE, playboy administrator Dong Xian catches the eye of Emperor Ai; in 1740, innkeeper He Shican is seduced by strange visitor Huang Jiulang; and at a circuit party in modern day LA, pre-med student River ends up in the arms of aspiring artist Joey. Though seemingly disconnected, the couples are actually living one epic romance constantly repeated across two millennia. Soulmates in a sense, their romances are nevertheless doomed. Rooted in one of the greatest, historically true love stories never told, their curse began with Emperor Ai and his male lover Dong Xian’s obsessive and destructive relationship that led to their deaths and the fall of the Han Dynasty. As their romance reincarnates, the couple begins to remember—and has the opportunity to recover one powerful artifact that might be able to break their tragic cycle.
