Lin Ye, the substitute mechanic of the "Po Feng" team, is the "little transparent" team darling cared for by everyone in the maintenance area - he speaks softly and is always squatting in the corner debugging parts, as if he has nothing to do with track racing. But no one knows that under her gentle skin is hidden the talented driver "Night Falcon" who retired from the race three years ago due to brake failure; nor does anyone know that she is lurking here just to find out the truth about the accident that year.
An accident occurred during the qualifying round, and his teammate's car nearly hit the guardrail. Lin Ye finally took off his disguise. Wearing a black racing suit, the engine of the "Phantom" motorcycle roared, and she drove the car to create an afterimage on the track. She not only saved her teammates, but also went straight to the surveillance tower where evidence was hidden. This attack not only exposed the hypocrisy of the captain Lu Chenzhou, but also completely moved the onlookers' technical general consultant Xie Yiyu.
As a representative of the team's investors, Xie Yizhen has a past hidden under his suits and ties - his sister passed away due to a conspiracy on the track. He returned to China with blood-stained gloves to track down the truth. He had already seen through Lin Ye's vest, but he silently paved the way for her: handing over key data and solving difficult situations.
The track is turbulent, with intrigue and passion intertwined. Lin Ye's sinister plan, coupled with Xie Yizheng's secret protection, the two of them will eventually find out the mastermind behind the scenes, restart the legend of "Night Falcon", and let the heart in the engine sound bloom with the cheers of crossing the line.
