An Intrusion is a 2021 American thriller film written and directed by Nicholas Holland and starring Keir Gilchrist and Scout Taylor-Compton.

[2][3] The week of Christmas, Rebecca Hodges is frightened in her home one night when she sees someone in a mask depicting a woman's face has broken in and has been watching her in the dark.

After the police leave, it is revealed through conversation that Sam doesn't trust his daughter and her relationship with a senior at school and that the family has been experiencing various degrees of vandalism in the week leading up to the incident.

He attempts to hide the information and his concern when his co-worker and brother-in-law Chris comes to his office before eventually deleting the email, believing the threat to be a bluff.

Meanwhile, Rebecca and her friend Mel pull her car over after leaving school due to a foul smell coming from the trunk while Layne watches from a distance.

He casually mentions that he has been also receiving threatening emails that he thinks are related but declines to allow Savannah to see them due to what says are "sensitive work matters."

Joyce and Rebecca watch as Sam alarmingly and violently begins to destroy the Santa Claus decoration with the baseball bat.

He then sneaks away in the car to bury Layne's body in the woods before returning home in a relaxed state and waking Joyce up to have sex.

The next day at work, however, Sam receives another email from the stalker containing pictures of him burying Layne in the woods, proving that he killed the wrong person.

Sam grows uncomfortable when the church and the Minister begin to hold a faith healing ceremony for a woman in the congregation who is a burn victim that they believed was the result of her recent infidelities.

Unsure if this is directed at him as well, he nervously sits through the ceremony until it ends and finds that it is entirely a coincidence, but as they prepare to leave, an unseen person with missing fingers touches him on the shoulder and wishes him a merry Christmas.

The police arrive and break the fight up and Sam receives a call from Savannah, who reveals she has convinced the man to drop the charges, but that she does not trust him at all now, she too then wishes him a merry Christmas.

The two happily share stories about love and loss while listening to Christmas music and drinking and Sam offers him relationship advice as the man talks about his own misfortunes in life.

Devin reveals that he is one of several stalkers who have been following him for some time and has enjoyed using Sam's personality traits against him, including his tendency to lie and hide things.

At the house, Rebecca and Joyce are being held at gunpoint outside their home by another man named Mason as Savannah and dozens of officers attempt to negotiate with him.

The police, Joyce, and Rebecca are forced to continue listening as Devin reveals that Molly's life spiraled out of control shortly after those events and that while living in poverty, she had three different sons with different men before ultimately committing suicide.

Devin tells him that poverty and the foster care system brutalized the three of them as children and that he and Mason's third brother was Corey, the man in the mask who Sam had shot the night before.

However, after several interested parties, including Gilchrist, came aboard after reading the script, the indie film with its meager $60,000 budget began to grow and widen into a larger production with a much wider scope.

[10] Cody Hamman of JoBlo.com gave the film a positive review and wrote, "The cast is quite good all around, with Hoveland doing some impressive work in the emotional moments she was given.
