After Lin Xiaoman was transferred from County No. 1 Middle School to a key high school, due to his ordinary family background, he became the target of bullying by Su Yuqing, a wealthy girl - her homework was torn up, ink was thrown on her, and she spread rumors and ate leftovers. When she hid in the laboratory building to clean her school uniform, she accidentally found an old Ricoh camera. The film recorded the cherry blossom specimens of the Astronomical Society in 2003, which was related to Su Yuqing's fake recommendation. The mysterious maintenance project Mo (a genius senior who was falsely accused of academic fraud) took her to repair the abandoned telescope and use science to fight lies: the prism experiment revealed traces of data adulteration, and the pulsar signal captured by the radio telescope became irrefutable evidence. In the end, Lin Xiaoman gave a speech "Light will not be broken down by a prism" at the morning meeting of the whole school, and Cheng Mo broadcast live astronomical observation footage, making the academic injustice that had been hidden for ten years come to light.
Purpose: "Cowardice hurts more than bullying, but the light of truth will never fade." ? Fight power oppression through scientific evidence ? The weak use knowledge to fight for dignity ? Healing and inheritance of intergenerational trauma
