Joseph is an airport security inspector, and his life seems ordinary. However, his daily work is boring, and the security conveyor belt continues to convey alienation and anxiety from passengers and colleagues. After an unhappy family gathering, a new unruly soul begins to erode the original him. The new Joseph acts recklessly and is always on the verge of emotional outburst and self-destruction. This is not only a desperate struggle for the protagonist's self-discovery, but also a portrayal of the lives of ordinary people in society. The film is shot in the form of handheld photography, and the oppressive shots make it easy for people to immerse themselves in the character's chaotic heart. Ben Whishaw's performance is very impactful.
