Chen Du, an elevator maintenance worker, has been in the industry for eight years. The work license is the passport, and the wrench is the only support.
Others are trapped in rules - he fixes them. Believe in your own wrench.
The escalator in the shopping mall accelerates for no reason late at night, the cage in the mine repeatedly falls, and the elevator on death row has extra buttons out of thin air... Every strange rule is a malfunction, and every repair is one step closer to the truth.
There is no system, no teammates, just an elevator maintenance worker who is even more unreasonable than the rules.
That day, he received the maintenance order that shouldn't exist.
