A cult called Wakwak headed by Papa Mundo is ready to kill and be killed to fight for their beliefs. It is a religious battle for their leader, clad in priest's robes, who they believe has supernatural powers to extinguish life out of anyone. Outnumbered, Lt. Cary Altamonte's group fights for the safety of the civilians. The situation unfolds in a battle of faith.
Unfortunately the movie Isang Araw Walang Diyos is not yet available on HBO Max.
