In the busy city, a bizarre case quietly unfolded.Li Meixian, a seemingly ordinary mother, is involved in a complex conspiracy.When her son Bong-seok entered the store, she deliberately pretended not to recognize him, hoping that her son would follow the plan.However, things didn't turn out as she expected.

Fong Xi did as he was told, but was accidentally discovered by a mysterious figure named Frank.Faced with the sudden crisis, Li Meixian was anxious, while Fengxi was in trouble.Just when Frank was about to take action, he suddenly received an order to cancel the operation and had to leave temporarily.

Afterwards, Lee Mi-hyun blamed Bong-seok for not following her advice, while Bong-seok explained that the mistake was caused by the battery of his mobile phone being out of power.At this time, Quan Qidao found a battery among the relics and accidentally discovered the truth about his father's murder.The murderer's face seemed familiar to him.

In order to find the real murderer, Quan Qidao decided to return to work at the bus company.By chance, he met Frank and immediately recognized him as his father's murderer.In anger, he frantically chased to the suburbs and started a thrilling fight with Frank.However, in the end he was killed because he was defeated by the murderer.

Frank was confused as to why the operation was cancelled, so he rushed to his next target, Jang Soo-won.In a thrilling chase, he successfully knocked down and crushed Jang Soo-won.However, Zhang Suyuan's recovery ability was beyond imagination, and he quietly climbed into Frank's car.When the two came to the suburbs to fight, Zhang Suyuan finally won, destroyed the important personnel's information and left the scene.

At the same time, Hee Soo hid the phone without handing it over, and Bong Seok followed his mother's order and did not take it back.Under Qiangxun's inquiry, the matter came to an end temporarily.When Bong-seok took the bus home, he unexpectedly discovered that the driver Quan Qidao was missing.

On the eve of the academic test, Hee Soo sent a message of encouragement to Bong Seok, and the two expressed their feelings to each other when they met.However, during activities in the gym, Xixiu encountered danger while practicing high jump.At this critical moment, Qiangxun rushed to protect her, but Bongxi was upset that he could not rescue her in time because he fell with a heavy object.

Seeing her son's depression, Li Meixian advised him not to follow his father's footsteps.However, as the case deepens, the disappearances of Feng Xi and Quan Qidao seem to be related to the mysterious Frank.Feng Xi decided to continue to pursue the truth and seek justice for his father and Quan Qidao.In the pursuit of this bus panic, can Bong-seok uncover the true culprit and find justice for his relatives?All this is still unknown.
