Bobbi Johnson is a young literary sensation facing her difficult second novel. Already dealing with a crazed stalker and her junkie ex-boyfriend, Bobbi is convinced by her publisher to use new smart editing software and finds herself going head-to-head with an artificial intelligence determined to write her book for her.

特殊化妝與特效師出道的英國導演保羅海耶茲，新作《鍵入魔境》將故事建立在充斥著人工智慧的未來社會，小說家芭比在出版社提供的超級電腦設備下，準備完成第二部作品，但隨著瘋狂粉絲不斷以自虐影片騷擾、截稿壓力，以及不受控制的科技，她逐漸分不清現實與幻象。保羅海耶茲僅運用了單一場景便完成拍攝，透過大量視覺效果與迷幻色彩表現出各種形式的誘惑、拉扯、依賴，成功創造出密閉空間裡獨有的壓迫感，令人不寒而慄。
