Su Nian scores 735 on the national college entrance exam, ranking third in her province, and could have attended Tsinghua University. On the day the results are released, her childhood sweetheart, Lu Shixing, lies about getting a low score to persuade her to give up a top university and accompany him to a second-tier college. The deception was orchestrated by Shen Ruoxi. Shen Ruoxi follows Su Nian to Beijing and repeatedly frames her, coercing her to withdraw from school, reporting her for plagiarism, and inciting online harassment against her. Su Nian unexpectedly discovers that Shen Ruoxi's father is her own biological father. Consumed by jealousy, Shen Ruoxi injures someone and commits a crime, receiving a five-year prison sentence. Su Nian joins a national key laboratory, where she perseveres with quantum error-correction experiments despite seven consecutive failures. At her Tsinghua graduation speech, she reflects on failure and an uncertain future, reaffirming her commitment to scientific research and recognizing that she has trustworthy people by her side.
