In 11th century China, the Emperor Renzong reigns his country poorly, neglecting state affairs while the government sinks into corruption and war rages at his borders, whose only protection left is the famous Yang clan. However, when the last man of the family falls, leaving the country open to its invaders, the clan’s formidable women take up arms to lead the army to victory and seek vengeance against corrupt officials.

Mr. Lin and Ms. Lin are the number one and number two in the field. They are neither friends nor enemies, but they ultimately join hands along with trusty assistant Le Qi as they track down an infamous thief who has stolen the 'Heavenly Emperor's Hand'.
