Kidnapped by masked assailants and left at an island filled with the ‘Afflicted’, Claire and Moira try to find safety. They have a bracelet on their arms which record fear. An unknown woman calling herself the ‘Overseer’, tracks them via video cameras.

The first half shows Claire and Moira sending out a radio message, while the second half shows Moira’s father, Barry, coming to the island to search for her. But things don’t go as expected, and the signal Barry had received was made months ago.
