Full Moon over Grand Realm

Since losing contact with her husband, Ngai Hei-yin, Tong Tze-heung has been residing with her brother King-wai at Fong Yan-kit’s home. King-wai is suspected of participating in the resistance effort against the Mongols, and is under investigation from none other than Tong’s own husband, Ngai. Re-united by chance after a long separation, Ngai wishes to rekindle their relationship, and so issues a pass for her. Aided by Siu-kuen and her brother, Lik Hang, King-wai are able to intercept key intelligence. In the process, Tze-heung learns that her husband has turned traitor and become betrothed to the daughter of General Temur.

The intelligence, as it turns out, was actually disinformation sowed as a ruse to uncover resistance personnel. As a result, Siu-kuen and King-wai are rooted out and put under interrogation and torture. Tze-heung ventures into the command post and, employing considerable wit, forces her husband to release the hostages. The group then keeps a low profile, living in a poor village and plotting what is to become the Mid-Autumn Insurrection. Under the command of Yan-kit, and with encouragement from Tze-heung, King-wai sends the signal for the army to crush the Mongols. During the raid, Ngai succumbs to a mortal wound.
