In a future version of Chongqing, rap prodigy Xiao Bu has walked away from the stage, withdrawn into himself since his sister left. His talent hasn't disappeared, only his will to use it, until a chance encounter with Angelina Jolie, a popular virtual idol, pulls him back toward the mic. With her push, Xiao Bu and his Keep Real crew set their sights on returning to the "45-Second Counterattack" rap battle, chasing the dream they'd put down. Built around battle rap and idol culture with a sci-fi edge, it's a story about picking a mic back up after quitting on it.
