Her next awakening happened a long time later. Mina slowly comes out of her coma, ending up in the hospital where she used to work. She only remembers that for some reason she must call her twin brother Jeirent, whom she has not seen for a long time, and she avoids her fiancé Mark, although he surrounds her with care. In the evenings, in the corridors, Mina sees the shadow of a young nurse in a uniform from the thirties, and birds appear in the ward again. Her only friend is Steven Adams, a local doctor. He brings her a book - the history of the hospital. And it is on these pages that Mina finds the first clue to the strange events that happened to her...
