Ib and Boum decide to commit suicide together in Bangkok in 1997. After reneging on the promise, the vengeful ghost of Ib returns 20 years later to haunt Boum and her 15 year old daughter, Bell.
The Promise, known in Thai as Puen.. Tee Raluek, is a 2017 Thai horror film directed by Sophon Sakdaphisit and produced by GDH 559/Jor Kwang Films. It stars Namthip Jongrachatawiboon and Apichaya Thongkham, and was shot in Bangkok's famously unfinished Sathorn Unique Tower.
