脱离卧底生涯的锋，以为两袖清风， 　　惟昔日阴影挥之不去，上司、女友、老父，统统投不信任票，一次枪声， 　　同袍继而倒地，原是江湖的昔日好友却变成陌路人。可怕的是锋也变成了自己的敌人，内心的煎熬令可卡因成了他最 　　直接了当的解脱。 　　滤镜下的灰暗色调、霓虹灯下的惨淡蓝、幻觉式FLASH 　　BACK。是绝望观感，还是在无人境界的国度？最危险的人 　　物，正是那个活在梦魇的自己。

In this powerful documentary, Mama Yang, an 84-year-old woman living in New York, finds herself in correspondence with 45 high security prison inmates she views as her own children. Most are Chinese American immigrants, and see in Mama Yang a mother figure they never knew before they stepped through prison walls.                                                                    　　For Mama Yang though, the story is about more than Christian charity. She had already lived a full life in Taiwan when her husband died at age sixty and her son lost their house in a financial blunder. She moved to the US to start anew and lives with a Taiwanese American granddaughter that remains distant. In a film marked by family separations, Mama Yang writes letters – whether to the incarcerated or to her own granddaughter – to heal lifetimes of wounds.
