As the title says, the video shows the tutorial that explains how to scare someone with 5 steps. At the first step called "Place a fake critter in their bed," A man sets up a fake spider at woman who sleeping in a bed. After a few seconds is passed, she's gets scared when she wakes up and sees the fake spider. At the second step called "Appear in a bathroom mirror," a man using mask and goes to bathroom to scare a woman. At the third step called "Imitate a confined space," a man puts the cardboard box to cover an another man's head who sleeping on the sofa. At the fourth step called "Hide your hand," a man is setting up a prank with cutting a hole into a candy bag. After that, the girls appears and one of them inserts her hand into the bag, then a man holds it. At the fifth and final step which contains a screamer called "Use the computer," a man watching K-fee commercials (which only shows the first few seconds) with a notebook and then a zoomed-in picture of Regan MacNeil from The Exorcist appears with a short scream. After the all steps was shown, the outro plays normally, but a few seconds has passed, the same screamer from the fifth step appears again, then the video ends.
