After five years abroad, Lin Shuying, a Ph. D. In Physics from Cambridge, returns to Shanghai.
Dressed in plain clothes and carrying an old box full of blueprints and parts, she looks like she has returned to school to teach, but in fact she has a secret mission - to develop a safer shortwave radio, and to preserve the hope of her country and her country in the precarious world.
The glitz and glamor of Shili Foreign Market remains the same, but the old friend has long been changed beyond recognition.
Gu Yunshen, a former classmate, has become a shipping giant in Shanghai and is surrounded by gossip. He expressed his goodwill to her when they reunited, but she was cold and rejected thousands of miles away.
She didn't know that Shang Wanru, a famous opera actor who Gu Yun was famous for late at night, had a similar facial features to hers.
Shang Wanru sings mellowly on stage, but is full of thoughts off stage. Shang Wanru understands that she is just a shadow substitute that others want.
On one side is the cold and rational scientific research mission,
On one side is the constant cutting of old feelings and the mystery of the substitute,
There are turbulent times outside, and there are undercurrents of heart inside.
Lin Shuying's return was never to renew the love between her children.
She wants to use knowledge as her blade and drawings as her armor in this glamorous Oriental Paris.
Find a way out that only belongs to her, to save the country and herself.
