The Crossing Hero is a time-traveling tale that follows the lives of Hong Xidong (Jiro Wang)--the leader of Ming dynasty Emperor Zhu Yunwen's personal bodyguard detail—and two imperial military guards, Peng Ze (Hu Yang) and Xu Xiaotian (Bruce Xie), who are hot in pursuit of a revolving pearl treasure in Hong's possession. All three time-travel into the 21st century, where Peng and Xu encounter Hong Xidong's identical future other, Hong Xiaodong (Jiro Wang). Peng and Xu's attempts to adjust to life in the future lead to a series of comedic adventures.
