The Green Hope

In a cold Christmas in 1996, the workaholic Fong Kin Choi has been sick in bed. His dying wish is to find his youngest son Ka Him, who lived with his mother due to the divorce 12 years ago. After 12 years, Kin Choi's olderst son, Ka Fai, found out that his younger brother suffers from mental illness due to their mother being drug abuser and forcing Ka-him to do illegal things since young age.
After his father died, Ka Fai took Ka-him in and helped him get back on his track as living as a normal person. Ka Fai notices his brother is a gifted musician, but his talent is hidden for years. With the help of Ka Fai, Ka Him's talent shows off and become famous pianist, recognized by other people. It proves that although he's a minor mentally ill patient, he can still live a normal life and being successful just like others.
Throughout the show, Ka Him's struggle to success was littered with failures and discrimination by others due to his disability. Towards the end of the show, Ka Him's effort was eventually recognised. The show carries an inspiring underlying message that people with disabilities can succeed, and disability discrimination only contributes negatively to their struggle.
