In a highly mechanized future world, humans are overly dependent on auxiliary devices, and traditional competitive sports are declining. The young girl Lu Xiaoguo is a "marginal person" who is obsessed with handmade models. Due to an unexpected debt, she has to join the "Blue Sky Football Club" which is on the verge of dissolution. She insists on not installing any sports plug-ins. She only relies on the sense of space and anticipation developed by disassembling the model to turn the ball path into a precise geometric model on the arena. Accompanied by her sharp-tongued agent Wen Xinghe, she started from scratch, in a future city full of steel and iron bones, using the purest physical strength to challenge the mechanical limits and reawaken all mankind's love for passionate sports.
