In 2026, Basman Group President Chen Mo is working continuous overtime for the "Basman Future City" project. While napping, holding a blueprint of an old-fashioned steel window in his hand, he wakes up to find himself time-traveled to the door and window factory in Nankang Street, Jiangdu City in the year 1986, becoming the 22-year-old temporary worker Chen Mo. The original body fell into a coma due to rescuing a fire in the workshop, and the factory is in debt, equipment is old, and workers have not been paid for half a year, facing the fate of being annexed by a state-owned large factory.
