那个我最亲爱的陌生人

绿树成荫，夏雨淋漓，小学生阿全的暑假作业是要观察鸡蛋的孵化，而他的家庭似乎也面临着变化：在成长过程当中缺席的母亲才从监狱假释，又回头去找当初要她顶罪的男友， 令阿嬷与妈妈的争执越演越烈；爷爷则被诊断出阿兹海默症，阿嬷看似无微不至的照顾， 更像在掩饰什么不可告人的秘密。此时，爷爷的旧友来访，看似友善温和的他，却掀起了 一阵家庭风暴⋯⋯There are many problems in the Zhang family, but one eventful summer changes many things. Zhang Junxiong is diagnosed with Alzheimer's, and that weighs heavily on his wife Wang Feng and the rest of the family. Zhang's daughter Xiao Meng is released on parole from a long prison term and struggles to reconnect with her illegitimate son Ah Chuan and her ex-boyfriend Ah Wen. A domestic crisis is narrowly averted when Zhang reconnects with his former aide-de-camp Cheng'en, a man for whom he has always harboured tender feelings. Paradoxically, the incident which does most to heal the family's wounds is the assassination of Ah Wen by a gangland rival. The Zhangs move to a new and better home. The young Ah Chuan is left pondering the meaning and value of memories.
