Ngoan plays Tam, a doctor, while Tuan portrays the spiritual practitioner Liem. The promotional material places them in a story about saving a child as secrets from Tam's past threaten his family.
The teaser shows the two men both clashing and working together, without fully explaining their relationship. Whether they remain opponents or allies throughout the film is therefore unclear. Lan Phuong plays Tam's wife.
The project brings Tuan back to a genre in which he has appeared repeatedly, while the doctor with a hidden past offers Ngoan another horror role. The promotional footage establishes the story's premise but does not reveal its full course.
