Jessamyn “Jess” Teoh is feeling aimless and adrift. Born and raised in the USA, she has just moved to Malaysia with her parents, and they’re staying with one of Jess’ aunts while her parents are looking for their own place to stay. Jess is unemployed, broke and hiding the fact that she has a girlfriend in Singapore. Her girlfriend wants her to get a job in Singapore, so they can be together, but Jess keeps lying to her about her job searches.
So when she starts hearing a strange voice in her head, Jess puts it down to stress. It takes a while for her to realise that the voice belongs to her dead grandmother, who used to be a spirit medium. Being mediums apparently runs in Jess’ family, having skipped Jess’ mother for some reason. Jess’ Ah Ma was the avatar of a mysterious spirit goddess known as the Black Water Sister, and now a local businessman is threatening the park where the Black Water Sister’s shrine lies. Ah Ma needs Jess’ body to stop this, and settle a personal score against the magnate as well. Soon, Jess discovers that Ah Ma takes over her body at night, so she wakes up exhausted. She needs to figure out how to make a deal with her dead gran’s ghost, before she ends up permanently possessed.
