故事聚焦在一支研究团队，他们被派到科拉深孔（Kola Superdeep Borehole）去调查源自于深处的奇怪声音，他们却发现超乎他们所有想像的东西。更糟的是，他们可能无意间将躲藏在深处的东西给释放了出来。
The story is carried by Mady, student by day, locksmith by night. But Claire, the enigmatic young woman she is helping out one night, isn’t what she seems to be. This door isn’t that of her apartment. And the bag she wants to recover at all costs isn’t hers, but Yannick’s, a man whose questions Mady will have to answer to. Caught in a hellish race, Mady only has one night to prove her innocence in a bustling city. One night to save her own skin.
