Jamie Waters (Elizabeth Reese Elizabeth Rice), a young woman who works as a journalist in Chicago, was suddenly told that her sister Anna (Rayann Condy), who lives in Singapore, committed suicide somehow. Shocked Jamie hurried to Singapore. She was saddened by the video of her sister's suicide. Although she never believed that Anna would choose this painful way, Anna's Huntington's disease from childhood seems to support the fact that she committed suicide. After that, Jamie meets his 12-year-old daughter Katie (Adina Herz), who is the witness of her mother's suicide scene. After Anna's cremation, a series of psychic events happened around Katie. She firmly believed that her mother had come back, so she tried to communicate with her with Morse code, but got in touch with a terrifying unknown being.
