Provincial debate champion Lin Zhuo is the "perfect sun" walking around the campus, but no one knows her silence for two years - her father was imprisoned for exposing corporate pollution, and she could only bury the truth into a black recording pen. The transfer student Shen Buyan has an absolute sense of music and can "hear" all the secrets of the world, but he built a wall of silence because he saw through the hypocrisy too early. When two people who choose silence meet, they use sound spectrum, Morse code and silent tacit understanding to fight against an empire of lies woven with "legitimate speech". This is a war on the truth, and their weapons are selective silence, scientific sound evidence, and the deep resonance of two souls in silence.
Purpose: To give voice to those who cannot speak, and to let those who are not heard be heard.
