This is the Covenant Symphony Orchestra and the last line of defense to protect the city.
Yun Qianxia, a hacker pianist who monitors the battlefield, Lin Ruoshuang, a cool position player who breaks the boundaries of the flute, Lei Lei, a violent drummer who shatters the sound, Pei Yan, a two-faced man responsible for low-frequency suppression, and the core duo - Gu Hanchen and Su Xiaotang!
When the original sound level crisis comes, the "Mute Club" attempts to erase all sounds and emotions in the world. All members of the symphony orchestra gather together to draw the sword!
"We play not to perform, but to declare war on gods and monsters!"
