Quiet music plays throughout the entire video. For the first 15 seconds or so, the screen is black, until the text "MONA LISA PAINTING HIDDEN MESSAGE" fades in. After a few seconds, we abruptly cut to a picture of the Mona Lisa painting. We zoom in towards the right side, next to Mona Lisa's head. At 0:32, the zombie from the K-fee car ad appears with his usual scream. We cut to a black screen, where we see the Trollface mocking us.
