Flat 3A tells the story of Fiqah (Intan Ladyana), a factory worker who is pregnant. Anas (Adey Shafrien), the boyfriend, forces Fiqah to undergo abortion. After that, Fiqah is overwhelmed by guilt and remorse that she moved to another flat with her friend Ratna (Shasha). Unknown to her, the house she's moving in was the base of a black magic shaman, Kang Suman (Zaidi Omar) and people there suspected Kang Suman was responsible for the disappearance of a little girl named Fatin.Fiqah is then haunted by a little girl in the house, who she says looks like Fatin. But Ratna dismisses her claims because Fiqah is still traumatised. Meanwhile, Fatin's mom (Kathy Azean) and uncle, Wahyu, who is an exorcist, carry on searching for her. Yet another horror movie... this one's from Azhari Mohd Zain, who brought us Santau and Mantra. Flat 3A's slightly different from the other two, but still kinda the same... especially the whole shaman/bomoh theme... guess he really can't run away from those elements.
