Near Dark starts with the transformation of a man named Caleb Colton into a vampire when a girl named Mae bites him on the neck. The next morning, Caleb’s body begins to burn as soon as the sunlight hits it. Mae then comes with a group of vampires and saves the burning Caleb. They take him to their coven where the vampire Severen decides that Caleb must die. However, Mae confesses that he is already one of them.
The group’s leader, Jesse Hooker, decides to give Caleb a chance though he is highly doubtful about the man.
