‘There’s Someone Inside Your House’ Plot Summary

The film kicks straight into the action. Jackson, wearing a jacket from Osborn high school, enters his house while talking to his friend Macon. He puts an alarm and goes off to sleep only to find out that something is not right. The door was open, and he sensed that somebody had broken into his house. He goes inside again and finds out that his pictures have been stuck on the house’s walls. These pictures were of a night when something gruesome happened. Jackson had beaten another guy from his school named Caleb. He was left with a broken jaw and severe injuries. Nobody knew about it until this moment. Jackson goes to his wardrobe area, where he is attacked by an anonymous guy who is wearing a mask that resembles Jackson’s own face.

The masked guy kills him and, at the time, sends the video of the fateful night to the whole school. The secret is disclosed, and now the whole school knows about it. People think that because Caleb was gay, that is why he was subjected to such discrimination and brutality. Caleb never reported the incident, and now he feels even more ashamed to face the whole school, who would be a passing judgment about his sexuality. People suspect that Caleb might have hired a killer since he was in the Football match when the incident took place.

Who was the Masked Serial Killer?

After Jackson, Katie was the next in line. She had saved a podcast where the notion of “white supremacy” was being discussed and also how there exists research work and data to prove that it is indeed reasonable and logical. There was speculation among the friends that Ollie was the culprit. His asocial behavior led everyone to develop a feeling of qualm against him. But little did the gang of friends know that the killer was among them laughing at their false assumptions.

Zach Sandford was the real killer. In the climax, Zach’s corn farm was set on fire. Ollie, Makani, with other friends reach there to save Zach. When they enter the corn maze, they find Zach standing there wearing a mask in front of his own father. He takes out his sword and pierces it inside his father. Makani and Ollie stand there dumbfounded, not able to process the course of things.

‘There’s Someone Inside Your House’ Ending Explained – Why did Zach kill everyone/his father?

Zach gives the reasoning behind his gruesome and terrifying acts of violence. He had been someone who was always scorned off for just being privileged. His father was among the most potent and opulent people in the town. But people treated him like it was his fault as he belonged to a privileged class. Zach wanted to show people that even they were two-faced and had a mask on their faces at all times. He wanted to show them that given an option, they also would want to be wealthy and privileged.

Zach says that he couldn’t shed off his family name from his identity. It was the accident of birth over which he had no control. But the victims whom he had killed always had the option of giving up their hypocrisy, but instead, they chose to put on a mask of pretentiousness and portray themselves to be morally upright.

Zach kills his father and thereby absolves his identity from his roots. Makani kills Zach in the end, who just fails to understand that he was the actual problem all along and not the ones whom he had killed.

In Conclusion

There’s Someone Inside Your House is a kind of film that tries to raise some critical questions but lacks the grooves and ridges in its narrative that are so essential to create a friction that holds the attention of the audience. Streaming on Netflix.

I came to Mumbai to bring characters to life. I like to dwell in the cinematic world and ponder over philosophical thoughts. I believe in the kind of cinema that not necessarily makes you laugh or cry but moves something inside you.
