In 1948, the colonial rule was high-pressure and harsh. The British army issued an emergency decree to encircle and suppress progressive forces. Overseas Chinese in Southeast Asia responded to the domestic May Day slogans, and waves of patriotic protests broke out. The Takeda brothers were in troubled times and abandoned their father's Kuomintang camp to join the armed struggle. The elder brother relies on traditional wisdom to coordinate guerrilla warfare, while the younger brother relies on chemical knowledge to develop ordnance and explosives. Father and son have completely opposite positions. The father was ordered to collude with the colonial forces and use family ties to set up a trap against the two brothers. The brothers saw through the conspiracy, used classical strategies to defeat the enemy's conspiracy, cut off the bonds of family ties and stood firm in their faith. The story draws on the past struggles of overseas Chinese in Southeast Asia to analyze the dangers of colonial power and explain the power of struggle between human choices and Chinese wisdom in troubled times.
