The fourth addition to the franchise sees the return of the army boys including Sergeant Ong, Lobang, Ken Chow and Aloysius, joined by a new female officer, as they are called back for in-camp training under the Armoured Formation of the Singapore Armed Forces. Hilarious situations happen when they are back training together and their military roles reversed. Their brotherhood is also put to the test when new enemy threats arise.

The story spans from 1965 to the early 1970s. Heavily pregnant Zhao Di, the unwanted second wife of an older man, was chased out by her husband's family and forced to return to her own family. She gave birth to a pair of twins, Shun Fatt and Su-mei. As Su-mei had two moles on her face, which was said to be bad luck, she decided to give her up due to the pressure of wanting to build a better life for the rest of her family.
