Bonded in their youth and separated by tragedy, an astronaut and a free diver bend the laws of space and time in their efforts to be together again.
A group of student want to challenge themselves by entering the most haunted building of their school, which is forbidden.
Nick, Bew, James and their friend are preparing for their university admissions, but because of James' less than desired results, he brings his friends to get the blessings of Mae Nak. Nick doesn't believe in Mae Nak and constantly makes fun of it. Suddenly, the group finds themselves in the realm of Mae Nak and have to find a way out to return to normality.
