Cadence, a talented rhythmist, can control the frequency of others' actions through exquisite rhythm. At the peak of her performance in the neon city of "Rhythm City", her drumbeat accidentally resonated with the city's deep energy - the "city heartbeat", triggering catastrophic synchronization: the actions and thinking of the entire city were forcibly unified, and society instantly solidified. Cadence, shrouded in fear and self-blame, becomes the only "free man". She must go deep into the core of the city, decipher the ancient code of the "city's heartbeat", find a unique "counter-rhythm" in the chaos and pursuit, and reverse the silent storm she has personally created. This is a profound adventure about the origin of rhythm, individual freedom and collective will. She not only wants to save the city, but also redefines her own power and responsibility.
