"Jiang Ling", a talented color neurological painter, has the extraordinary ability to tune and remember colors. She was invited to restore the memory paintings of abused children that had been smeared gray by trauma, but with the delicate brushwork, she was shocked to realize that her employer "Mo Fei" was actually an accomplice who covered up the evidence of the abuser. Jiang Ling, who refused to be silent, teamed up with the insightful child psychologist "Lin Che" to use color as a weapon: they developed "color exposure therapy" to reveal hidden traumatic memories under a special filter; they developed "memory tamper-proof paint" to leave an indelible texture on reality under ultraviolet light. Instead of resorting to violence, they founded the "Memory Forensic Appraisal Center", using colorful neurological evidence to leverage the cold judicial system, turning the strokes of art therapy into thunder to promote child protection legislation, and giving a background of defending silent childhood.
