Su Min's mother Yingling participated in the game experiment of "Island in the Sky", but disappeared because of the "Countercurrent Waterfall" project in the game "Island in the Sky". The search was fruitless and there was no news at all, so the official was forced to give up. Many years later, Su Min returned to the game "Island in the Sky" that her mother had played back then to find her mother who was lost in the "Counter Current Falls". However, she unexpectedly joined Jane's game team and met Qin Xin, who was also trapped in the game.
Su Min and Jian came to South Korea to participate in the competition. They accidentally discovered Luo Xi from the former team on the playground, and they formed a fateful alliance. Together they entered the game to find their master (captain) N and his mother. But there was still no result, and Su Min also missed the finals because of his search for the truth. However, there was one person who was willing to give up his qualification to Su Min, and that was the official hacker: Qiong! Although he didn't know why, he was willing to give up his spot to Su Min, but this opportunity still required Luo Xi's help to win the game.
Concept: Love and games are recognized by the world side by side, but they lost to the words "give up"
