The drama series takes place around the days of the Nationalists' Republic of China, and also Warlord Era and World War II.

The story begins in a small village in the 1920s with Sau Hau (Amy Chan) becoming a servant for the powerful Fong family who owns a winery.

The Fong family takes a liking to her and arranges a marriage between her and their eldest son, Ho Sang (Steve Ma) who is away on a trip in Guangzhou.

Meanwhile, while on his trip, Ho Sang meets Man Fung (Sheren Tang) who has just been sold by her mother from the village unknowingly into prostitution.

When Ho Sang returns to his village, he is furious at the arranged marriage to Sau Hau but eventually agrees due to his mother's illness.

Ho Sang makes the decision to enlist in the army for the Northern Expedition and leaves his home behind to the disapproval of Man Fung, Sau Hau, and his family.

When Man Fung returns home to her mother, she is discovered by the village and almost killed by Sai Fan (Paul Chun) for being pregnant as a single woman.

Years later, Ho Sang returns home, married to Ding Man (Maggie Shiu), a nurse he met during his time in the north.

Ho Sang discovers his friend Lok Ping (Wong Chong Kwan), who he met during the Northern Expedition, is a guerrilla helping the Chinese Army.
