The teaser trailer was for a thriller film called Enigma about a university student whose parents die in a car crash and his brother is then kidnapped. The trailer uses an open narrative, revealing some key plot points like the car crash and kidnapping, but leaving much unspecified to intrigue audiences. Roland Barthes' theory of how codes generate and maintain interest is reflected in the teaser's use of an open narrative and hermeneutic codes to spark discussion and mystery without giving too much away. The unique storyline of the main character having tasks to complete to find his brother acts as a selling point for the film.
