Jiang Na-lu is a sixth-grade student at Han River Elementary School and a freestyle swimmer on the school's swimming team, having won medals at the National Youth Games. She has been learning to swim since childhood and works harder and more diligently than anyone else. However, one day a strong opponent appears in front of her, and no matter how hard Na-lu tries, she cannot defeat them. For the first time, Na-lu tastes the feeling of repeated defeats and her mentality finally becomes unbalanced...

This is a story of a young person's growth through continuous competition and failure. To prove the value of their sweat and not to be a deserter, Na-lu works harder than anyone else. However, she blindly moves forward and forgets to occasionally stop and examine her own heart. Finally, with the companionship and encouragement of friends and family, Na-lu gradually realizes the significance of failure for growth. The "fifth lane" she is in is not a place to stand still, but a stepping stone to stand up again, a place to move forward and grow.
