Peter (played by Sean DeGuzman) is a photographer for weddings and events. However, in his spare time (many recently), he strolled in a picturesque remote lakeside camping area where couples came to camp outdoors. Peter will track these couples and secretly take videos of them having sex while getting off the car. Then, he will publish these sex videos on an online pornographic website to make money from them. One day, Peter followed a young woman named Mia (played by Kara Gonzalez) and filmed her while she was taking a shower. Mia was not angry, but on the contrary, she was very friendly to him. However, she has a hot tempered and sinister looking boyfriend RJ (played by Joseph Elisard) around her, who doesn't like Peter being with his girlfriend. The next time Peter secretly filmed a video of Mia having sex with RJ, he witnessed Mia suddenly slashing RJ's neck.
