Tiwa, having met with problems at work and love, he goes to visit the place where he first met his girlfriend. There, he met Fah, a beautiful girl in a Thai dress. During his stay at the resort, there were many people who committed suicide by jumping into the river believing that the ghost in the red dress took them. The police then investigated the 6 suicide cases and found out that they raped Fah and threw her into the river from the same bridge. Tiwa was shocked when he saw Fah in a red dress and would like to find the successor to let he go on Loy Kratong day. Tiwa doesn't want her to do this but he also wants to help her so he would sacrifice his soul. It all depends on Fah's decision, watch what happens in Successor.
