'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.

Parjo, a truck driver who rarely comes home, struggles to resist the temptations he encounters on the road, especially those related to sex. It’s not that Parjo lacks desire, but rather that he strives to be a good husband to his wife. This time, however, things are different. When Parjo finally returns home and wishes to fulfill his sexual needs, unexpected situations arise—his attempts are constantly interrupted as his child frequently wakes up due to pinworm discomfort.
