The shot where the male character first appears and walks over and talks to the female is the action code in the trailers narrative structure. This is because it sets up the story and leads the plot on because it is obvious that something is going to happen between the two characters. The audience are aware that something will happen but they aren't sure what or when so it leaves them interested and anticipating. Both enigma and action codes are stereotypical of trailers as they are designed to set up a scene and then lead the narrative on smoothly and clearly so that the audience know roughly when the key parts of the narrative will occur, but the plot isn't completely given away. Therefore, I have tried to follow this convention by including these codes in my trailer.
