Su Wanqing, who comes from a small town, was admitted to the Cultural Relics Restoration Center under the State Administration of Cultural Heritage with first place in her major and became an intern restorer. She originally wanted to settle down and make a living based on her passion and skills, but she found that the interpersonal relationships here were complicated and factional struggles were fierce. On her first day on the job, she was regarded as a thorn in the side by her colleagues with background because of her outstanding talent, and was framed for causing a flaw in an important repair work. Faced with the crisis of being fired, Su Wanqing did not back down. She analyzed calmly, used her professional knowledge and proficiency in rules and regulations, and cleverly found evidence. Not only did she clear her grievances, she also made the mastermind behind the scenes suffer a hidden loss, attracting the attention of the deputy director of the department.
