Mila (Laras Sardi), an elderly caregiver, has been dismissed from the nursing home where she worked. Her boyfriend, Bimo (Roy Sungkono), works at a mobile phone credit kiosk. One day, Bimo meets his old friend, Ranty (Agnes Naomi Shivapriya), who is looking for a caregiver to look after her mother while she travels to Singapore for two weeks. Bimo tells Mila about the job opportunity. Since the job is only for two weeks, Ranty offers a very attractive salary. Mila agrees to take care of Ranty’s mother, Anggini (Dayu Wijanto). However, Anggini suffers from schizophrenia and dementia. The two weeks in the house feel much longer as Mila is terrorized by a series of strange occurrences that even threaten her life.
