安娜在床上醒来，脑袋因为前一夜的狂欢有些昏沉疼痛。她打开手机，发现新增一款名为“伊丽丝”(IRIS) 的神秘互动APP；它将好姊妹出轨的证据偷拍下来，还将不雅照、私密影片和讯息散布至脸书，监控她的生活，周遭朋友纷纷卷入，陷入恐慌。
　　安娜用尽一切办法，欲将伊丽丝移除，却引来致命杀机。不甘居于劣势的她，决定正面迎击…。

　　You wake up in a shabby hotel room with no idea how you got there. You can’t recall your name. You discover there seem to be other young women in other rooms in the same predicament, though one of them seems to know your name: Anne. After an unpleasant encounter with a rather large cockroach, you have a screaming fit. That’s when the nurses arrive to sedate you. And by the way, when night falls, you’ll need to escape from a killer demon with the bloodied head of a deer.
　　Faces of Anne relies heavily on elements of the slasher film – and in many ways, that’s exactly what it is. But the film is also a puzzle, whose central question – Why is Anne here? – allows us to explore theories as to its solution until the very last moment. Are we inside a video game? An escape room? The mind of someone with multiple personalities? The elaborate and nihilistic fantasy of a deranged serial killer? It’s nothing new to remark that the best horror films are often those that reflect the fears of society; this film builds a clever – and viscerally terrifying – analogy of some of the difficulties faced by today’s young people.
