"The Execution"; also released as Naked Massacre) is a 1976 horror film directed by Denis Héroux, and starring Mathieu Carrière, Debra Berger, and Christine Boisson.

Its plot follows a disturbed American Vietnam War veteran who, after arriving in Belfast, terrorizes a house full of international female nursing students.

The screenplay is loosely based on the crimes of serial killer Richard Speck, who murdered eight nursing students in Chicago, Illinois in 1966.

[2][3] In late 1972 Belfast, during the early stages of the Northern Ireland conflict, a disturbed American soldier named Cain Adams arrives after deserting in the Vietnam War.

Meanwhile, a group of eight young international female nursing students—Bridget, Christine, Leila, Jenny, Pam, Amy, Catherine, and Eileen—are preparing for their last week of exams before graduation.

Meanwhile, unbeknownst to the women, Cain returns to the house and breaks in through a downstairs window, confronting Jenny and Christine in the living room.

While doing so, he recounts anecdotes from his childhood, including his aunt telling him he was "born for hell" because he regularly missed Sunday church services; on his arm, Cain shows the women a tattoo he has of the phrase.

Cain brings her downstairs, showing her the corpses of her friends before seating her at the kitchen table, feeding her a piece of Eileen's birthday cake.

Later that morning, he watches from a nearby pub as paramedics remove the bodies of the women from their house and listens to locals discuss the murders.

Cain regains consciousness as the surgeon cleans his blood-covered arm, revealing the "born for hell" tattoo.
