Zhao Tiezhu, reborn in 1998, was exploited to death of exhaustion in his past life. In this life, he transforms into a welder making a comeback to chase his dreams. He touches Lin Xiaolu with his original vocals, but consecutively encounters Liu Dana, Boss Qian, and others framing him for stealing materials, slandering him for plagiarism, forcing him to sign unfair contracts, obstructing him from entering competitions, and even kidnapping and threatening him. Singing his way from the factory competition to the national stage, with the support of his coworkers and Lin Xiaolu, Zhao Tiezhu ultimately shatters prejudices and proves that ordinary workers can also use their talent to make their voices heard.
