‘Isyarat’ takes the innovative approach of bringing together five young directors, Asmirandah, who made Teman Bayangan (Shadow friend); Monty Tiwa (Lost and Found); Adhyatmika (Flora); Donny Alamsyah (Tanda Bahaya or Alarm); and Reza Rahadian (Gadis Indigo or Indigo girl), to create a series of separate but interconnected supernatural tales.
