"The setting is a derelict ship stranded on a beach in the middle of the ocean. The player, an anonymous person, is mysteriously locked in the operations room with doctor Lea Nichols, the only survivor of the said ship. The player first finds Lea Nichols through the camera lens when she wakes up from her room. After a brief introduction of herself, she is reluctant to trust the player with valuable information (such as the login details to her computer account). However, since the player is the only person still alive beside her, she has to rely on them for her survival. During exploration with Nichols on the ship, she finds the remains of her old colleagues and occasionally, recollects some memory fragments of an experiment subject called '112'." "With the use of a sophisticated security system the player helps the main character, Lea Nichols by telling her where to go, by turning lights on and off, opening doors, entering codes, controlling helper robots, and reading the torrent of files, email, and codes you are given. Not all the e-mail contain helpful information, neither are all the cameras useful, some having fallen objects obscure the view or being otherwise non-functional. The game keeps a log of real world play time with Lea noting how many days long you've kept her waiting since last playing."

Note: You also nod or shake your head by doing the same with the camera, because you can't speak to Lea.
