Reborn in 1988, Zhao Xiangnan wakes up to find his sister-in-law forcing his fingerprint onto a roster, trying to make him take his older brother's place in a dangerous mine where the roof is unstable. In his previous life, he was crushed and left with a broken leg and pneumoconiosis. His family used his compensation to live comfortably, yet complained that his medical expenses were too high. This time, he exposes their scheme in front of everyone, tears up the substitute shift list, and opens his own repair shop through his hard work. As the miners' lamps light up one by one, he finally understands that in this life, his fate must remain in his own hands.
