Scream... and Die!

London fashion model Valerie Jennings travels into the countryside with her boyfriend, Terry, who is searching for an abandoned house. They discover the house at nightfall, and while exploring it, Valerie discovers numerous women's passports in a bedroom. Another couple—a woman and an unseen man—enter the house, and Valerie and Terry hide in a closet. They watch as the woman is brutally murdered with a switchblade. The next day, Valerie reaches a road and hitchhikes back to London. She finds Terry's car parked on the street, and inside discovers her modeling portfolio with a photo missing.
