Spirits of the Mekong River

Dr Akkanee and his crew travel to a village that is old fashioned and superstitious to study the paranormal and that proves that it is not true. In the village, he meets and falls for a girl named Buapun. He is curious about her since he often dreams about her before coming to the village. The village is close to the Mekong River, which the villagers believe house spirits and deities. This is true as a spirit of a vengeful princess resides underneath the river waiting for her betrothal, which is the reincarnated Dr Akkanee.
