Red Passage 2014

In 1970, during the height of the Cultural Revolution in China, Hong Kong student Chan Wah-Keung gets transferred by his father to a leftist school that follows the teachings of Chairman Mao rather than the British colonial government's education policy. Branded a bourgeois by his stern and zealous homeroom teacher, Wah-Keung has a hard time fitting into a school system where he must wave the Little Red Book and write self-criticisms for his many mistakes.
