《第四公民》将能高度还原“棱镜门”事件始末，为观众真实揭秘身处漩涡中心的爱德华·斯诺登。
纪录片导演柏翠丝本人也是“棱镜门”事件的核心人物，正是在她和《卫报》记者格仑·格林沃德的协助下，斯诺登才得以将美国国家安全局的监控丑闻公之于众。而柏翠丝与格林沃德也因此荣获普利策奖。片名“第四公民”（citizen four）正是斯诺登早期与柏翠丝邮件沟通时使用的匿名代号。2013年6月，当柏翠丝第一次飞往香港与斯诺登见面的时候，她随身携带的摄像机也真实记录了当时的场景。《第四公民》将能高度还原“棱镜门”事件始末，为观众真实揭秘身处漩涡中心的爱德华·斯诺登。

Unraveling like a lush, gripping novel that constantly subverts expectations, The Oath is the interlocking drama of two brothers-in-law, Abu Jandal and Salim Hamdam, whose associations with al Qaeda in the 1990s propelled them on divergent courses. The film delves into Abu Jandal's daily life as a taxi driver in Sana’a, Yemen, and Hamdan’s military tribunal in Guantanamo Bay prison. Abu Jandal and Hamdan’s personal stories—how they came to serve as Osama bin Laden’s bodyguard and driver respectively—act as prisms through which to humanize and contextualize a world the Western media demonizes. As Hamdan’s trial progresses, his military lawyers challenge fundamental flaws in the court system. As charismatic Abu Jandal dialogues with his son, Muslim students, and journalists, he generously unveils the complex evolution of his belief system since 9/11.
Exquisitely constructed so multiple threads and time periods commingle seamlessly, and gaining astonishingly intimate access to subjects and information, The Oath illuminates a realm too long misunderstood.
