At the end of the Republic of China, Su Qingying, a famous film queen and underground intelligence agent in Shanghai, mysteriously disappeared in an explosion. However, her soul traveled through time and space and possessed a 22-year-old modern female bodyguard a hundred years later. When she woke up as Lin Wan and faced this strange world, she accidentally rescued a seriously injured and retired special soldier Lu Tingxiao, a 28-year-old "uncle" who was six years younger than her but had a strong aura.
Lu Tingxiao was once a sharp sword in the army. He was forced to retire due to serious injuries in the mission, but he accidentally got involved in the urban underworld dispute. When he discovers that the woman who rescued him is not only good at fighting, but also often speaks old Republican idioms and possesses lost martial arts, a duel between two powerful men and redemption spanning time and space begins.
She needs to adapt to modern life, and he needs to get rid of the shadow of the past; she needs to find out the mystery of time travel, and he needs to find out the mastermind behind it. When the wisdom of the movie queen of the Republic of China is combined with the force of modern special forces, the two independent and powerful souls heal each other's scars in the collision, and jointly face numerous crises from the underworld, the business world and even mysterious organizations.
