Dad Left Something Running in Bite Size Terror's Resonance
A storm, an unfinished experiment, and one very suspicious bathtub make clearing out Dad's house much harder than expected in Episode 4 of Tubi's short-form horror anthology.
Watch NowMaddy's father is gone. His work isn't.
While clearing out his house with her husband Ryan, Maddy discovers a strange device connected to the bathtub in Resonance, Episode 4 of Bite Size Terror. There's no instruction manual waiting beside it. No father left to explain what he was building. Just an unfamiliar machine, a house full of things to sort through, and a storm making the timing feel particularly rude.
We first flagged the suspicious bathtub situation in our Bite Size Terror preview article, but the device is only the beginning of what makes Resonance unsettling. Maddy came to close out one part of her father's life. Instead, she finds evidence that something he started may still be very much in progress.
The episode is only 10 minutes long, so we'll leave its biggest turns where they belong. Consider everything below a closer look at the machinery rather than permission to drain the whole tub. Tubi's Terror on Tubi has more reasons to distrust the ordinary once you're finished here.
“Turn on the water. Let’s see what answers.”
You Can't Ask the Person Who Built It
There's a particular frustration built into finding something important after the one person who could explain it is gone. Maddy can inspect her father's machine. She can follow wires. She can make guesses about what he was attempting. What she can't do is ask the obvious question: What were you doing?
Resonance gets mileage out of that missing conversation. Her father's absence leaves an information gap that no amount of rummaging through the house can completely fill, turning the device into more than suspicious equipment. It's evidence of a side of his life Maddy may not have fully known, sitting among belongings she's supposed to be deciding what to keep and what to throw away.
Curiosity becomes harder to separate from grief under those circumstances. Walking away from the machine could mean abandoning something that mattered deeply to him. Investigating it offers the possibility of understanding him a little better after it's already too late to have the conversation properly. Horror knows exactly what to do with that temptation.
The machine doesn't need to lure Maddy toward it. Her relationship with the person who left it behind already does some of the work.
The Experiment Has a Delivery System
Whatever Maddy's father discovered, he didn't leave it contained inside a beaker. His device uses water.
Suddenly, unplugging the machine doesn't sound like a complete solution. Once something can travel through an element as ordinary and necessary as water, avoiding the equipment doesn't necessarily mean avoiding what it can do.
Writer-director Mark Lammerding also surrounds the discovery with a storm, putting the same element both inside and outside the house. Water isn't merely where the experiment happens; it becomes part of the atmosphere pressing against the characters from every direction.
There's a nice bit of scientific horror hiding in the episode's title too. Resonance involves one system responding to the frequency of another. Without turning the short into a physics lesson, the idea fits a story where something transmitted can make another body respond. Maddy and Ryan aren't simply standing beside her father's experiment anymore. They may be part of it.
Behind the Bite
Lammerding has 10 minutes to move Resonance from clearing out a family home to full sci-fi horror, leaving very little room for a slow runway.
Much of that escalation falls to Glenda MacInnis and Andy McQueen. MacInnis keeps Maddy emotionally tethered to the reason she's in the house in the first place, while McQueen gives Ryan a different perspective on the increasingly strange situation. Their performances help the short change gears without making the characters feel like they've suddenly wandered into a different story.
Lammerding also gets plenty of mileage out of keeping the action contained. A house being emptied should feel like it's becoming less claustrophobic as boxes disappear and rooms clear out, but the storm outside effectively closes the world back in. Instead of expanding the short with more locations or a larger mythology, the environment makes the space Maddy and Ryan already occupy feel harder to escape.
Charles Halford contributes voice work, with Laura Leal producing. The small cast and contained setting suit the anthology's bite-sized format particularly well: Resonance doesn't need to build an entire scientific universe around its premise. It only needs enough time for one strange discovery to make an ordinary house feel very different from the one Maddy walked into.
