一名单身妈妈无户口又无房，她想找到一所能收女儿上学的小学；另一边，一所学校的墙边，被挖出了一具陈年遗骸。青年导演郭大路自编自导的悬疑片，曾在《后宫·甄嬛传》中以安陵容一角大火的陶昕然监制并主演。本片突破了留守儿童题材电影，融入浓烈的犯罪元素，聚焦于已成年的昔日留守儿童近况，以母亲替女求学和警方调查遗骸双线交汇，通过碎片化的剪辑打乱回忆与臆想、过去与现在的时空，让案件真相随着调查对象的不断增加而愈发迷雾重重，在冷峻克制的基调下，逐层暴露出在夹缝中生存之人所受之苦。

While a policeman is investigating the discovery of the remains of an apparent murder victim, a single mother is struggling to get her daughter into school. Presented at the Shanghai Film Festival, Within is a thriller that paints a poignant portrait of a China where social injustice determines a child’s future.
