A Wing Chun girl in a cyber world, punching everyone who looks down on her into the ground.
Zhou Yulu, the “problem girl” from the lower city, has inherited her grandfather's Wing Chun skills. When she steps in to save a rich heiress from harassment, she knocks out more than twenty martial arts school thugs in a minute, earning the school's master as a vengeful enemy. Her parents pressure her to become a nurse, while deep down, she's terrified of failing and being laughed at. As Western boxing closes in, can the ancient art of Wing Chun help her make her own voice heard?
