Inside is a 2016 English-language Spanish independent horror film directed and co-written by Miguel Ángel Vivas, written by Jaume Balagueró and Manu Díez, and starring Rachel Nichols, Laura Harring, and Stany Coppet.

In suburban Chicago, Sarah Clarke suffers a car accident during the third trimester of her pregnancy, which leaves her husband dead, and her partially deaf.

After falling asleep that evening, Sarah awakens to a knock at the door from a woman claiming her car has broken down.

After assuaging Isaac's worries, the woman attempts to usher him out of the house, but they are met by Sarah's mother who has just arrived by taxi.

Sarah again locks herself in the bathroom, and begins experiencing extreme labor pains, as the woman stabs at the door repeatedly.

The woman blocks the bathroom door with a chest of drawers before breaking into Isaac's house and slitting Brian's throat.

Moments later, police officers Mike and Alice return to the house to do a wellness check, and the woman poses as Sarah.

Noticing the door is ajar, Alice enters the house and finds Mike's body, while the woman accosts Sarah, who is hiding under a bed.

The woman subsequently shoots Alice dead with Mike's gun moments after Sarah's water breaks.
