Inside - 2007 [Kosjeyr]

A baby in utero is seen, with the mother's voice heard soothing it. The baby recoils as if struck. Expectant mother Sarah (Paradis) has been in a car accident, and her husband has been killed. Months later on Christmas Eve, Sarah is making final preparations for her delivery the following day. Still reeling from her husband's death, Sarah is now moody and depressed.

That evening, a mysterious woman (Dalle) arrives at Sarah's door, asking to use the telephone to call for help. Sarah lies that her husband is sleeping and she does not want to be disturbed, but the woman tells her that she knows that he is dead. When the visitor persists on coming in, Sarah, a professional photographer, attempts to take her photo through a window and telephones the police. When they arrive, the woman has already vanished. The police assure Sarah that she will be fine, but arrange to have a patrol car visit throughout the night.

Upon developing her photos, Sarah recognizes the woman in the background of an earlier photo she had taken, indicating she was stalking Sarah. Sarah telephones her employer, asking to have the photos enhanced. As she goes to bed, the woman arrives in the bedroom, awakening Sarah with scissors puncturing her pregnant belly. Sarah fights the visitor off and locks herself in the bathroom, where the woman tries to gain entry. The woman makes clear that her intentions are to take Sarah's child for herself.

Sarah's employer arrives, and later her mother, both unaware of the predicament that Sarah is in. Believing her to be the attacker, Sarah accidentally kills her mother by stabbing a needle into her mother's neck. Her employer is later stabbed to death by the mysterious woman. The police arrive to check up, and upon realizing what is going on, attempt to apprehend Sarah's assailant and are instead murdered.

A final confrontation ensues between Sarah and the woman, with both of them injuring each other via various household appliances. Sarah manages to gain the upper hand on her attacker and burns off half the woman's face with an aerosol container and cigarette. The woman flees, and upon being cornered by Sarah, reveals her identity; she was the other driver in Sarah's car accident and, being pregnant at the time, had lost her child.

The two are interrupted by the revival of one of the police officers; having been shot in close proximity by the woman with his riot gun, he survived the attack and was brain-damaged instead. In his current state of mind, he confuses Sarah with her attacker and brutally beats her in the stomach with his club. The woman comes to Sarah's aid and kills the officer, but it is too late; Sarah has begun to give birth and the baby is stuck.

Desperate to save the child, the woman proceeds to perform the impromptu caesarian section on Sarah with her scissors as she originally planned. With Sarah lying dead on the stairs, drenched in blood, the woman, having been successful with her delivery, sits on a rocking chair and comforts the newborn child.
