The opening of the trailer establishes the slasher/psychological horror genre in several ways. It begins with a close-up of a car and unsettling sound that creates tension around an unknown figure. Text then appears saying "who's out there?" implying a stalker or killer. A low angle shot reveals only the legs of this unknown figure, leaving their identity a mystery. Following shots introduce typical slasher film stock characters of teenagers and show the villain stalking a victim, conforming to conventions of the slasher genre.
