Summa: Dendam Perempuan Sinting

Four students majoring in nutrition, Tristan, Denisa, Reno, and Sigit, carried out field research in Kampung Tenung, a remote hamlet. They were allowed to stay overnight in a rickety hut belonging to Mak Summa, an old widow who lives alone with her daughter who was born with a serious mental disorder. Everything turns into a nightmare when Tristan and Reno commit despicable acts against the helpless Nini. This serious violation awakened another side of Mak Summa that had been sleeping for a long time: pure bloodthirsty madness. As a result, the four students were trapped in a deadly terror, fighting desperately to defend their lives from the wrath of a mother who had lost everything, including her sanity.
