Siapa Tutup Lampu?

5 friends (Akmal, Arif, Aryana, Azie and Amir) who are on holiday in Genting Highlands. On the way home, they were involved in an accident that killed Amir. The other four of them had to be present at the morgue to make an identification of Amir's body. While waiting for the doctor in the morgue, they were locked out of the morgue. As long as they are locked in the morgue, they are often plagued with various mysterious disturbances.
