On Xiafei Road in Shanghai during the Republic of China, Lin Xu and Shen Xingmian got to know each other because of a "goodbye". The bicycle bell, scrambled eggs with perilla and the agreement on the field bank became the warmth of their youthful days. Later, Lin Xu went to France and lost contact with Shen Xingmian. When they reunited eight years ago, Lin Xu was a special commissioner of the Kuomintang, but Shen Xingmian hid his underground party identity, and there was an undercurrent surging under the sweet marriage. But then there was a breakout, and everything changed...
Purpose: Through Lin Xu and Shen Xingmian's emotional entanglements and fate ups and downs arising from different beliefs and positions in a special era, to explore the inability of individuals to do so in the current of the times, as well as the persistence and choice of love in the face of the collision of beliefs and the righteousness of family and country.
