Harley David is a friend and co-worker of Laurie Strode and Mya Rockwell. On Halloween night, Laurie comes to Mya's home where she and Harley learn that Laurie is actually Angel Myers, the sister of Michael Myers. Harley at first believes Laurie is joking until Laurie shows them the book with her picture in it. The three go to a costume party, while there Harley hooksup with a guy in a warewolf costume and goes to his van to have sex. Right before they get started he says he has to take a piss. While he pees he is killed by Michael Myers. Harley is still in the van drinking when Michael breaks the backwindow. He grabs and strangles her and she dies within seconds.
