The file name itself has become a meme within analog horror circles. To say “That’s very Under Soles” means a piece of media that defies easy explanation, mixing childhood innocence with visceral body horror. Fan art on Tumblr and Pixiv reimagines Katelyn as a stoic warrior, the Ant Men as Lovecraftian drones, and the “soles” as a portal to a dimension of forgotten things.
Speculation continues. Some believe “SolemnPilgrim99” was a film student at NYU who disappeared before graduation. Others claim the video was a proof-of-concept for a video game that never left alpha. A few weeks ago, a Twitter account with the handle @UnderSoles posted a single image: a photograph of a dusty Windows XP desktop with the “Katelyn VS Ant Men - Under Soles.wmv” icon selected. The caption read: “She’s still fighting them. Under the soles.”
In the vast, decaying archives of the early internet, certain file names trigger a unique blend of nostalgia and dread. Unlike the polished trailers of Hollywood or the algorithm-friendly titles of modern YouTube, the raw .wmv extension speaks of a bygone era: the age of Windows Movie Maker, shaky webcam footage, and creepypasta that lived on USB drives passed between friends.

Without CGI—using practical effects of black construction paper and stop-motion—small humanoid figures emerge from the floorboards. The “Ant Men” are not literal ant-people. They are shadowy, two-foot-tall figures wearing inverted ant heads as masks. Their movements are jerky, sped up to 2x speed, creating an inhuman skittering effect.
The film opens with a low-angle shot of a pair of worn sneakers (the "Under Soles" of the title). The camera pans up to reveal a young girl, Katelyn, sitting on a twin bed in a room wallpapered with faded roses. The audio is a low hum of a CRT television tuned to static. Katelyn whispers, “They’re coming from under the soles.” It is unclear if she means shoe soles or soul as in spirit. The file name itself has become a meme
The creator appears to be a user named “SolemnPilgrim99,” active on a now-defunct horror forum called . The original post read simply: “My little sister Katelyn had a nightmare about the floor turning into teeth. We made this. It’s not a game. It’s just... a warning. Katelyn VS Ant Men - Under Soles.wmv” No further context was given. The thread was locked in 2009, but not before the file was mirrored across early file-sharing networks like LimeWire and Kazaa under increasingly bizarre misspellings. Plot Summary: What Actually Happens in the Video? Attempting to describe “Katelyn VS Ant Men - Under Soles.wmv” is like trying to explain a half-remembered dream after a fever broke. The video runs exactly 4 minutes and 33 seconds (a deliberate nod to John Cage's silent piece, or just a rendering glitch?).
Katelyn arms herself with a flyswatter and a desk lamp. The fight is clumsy and intimate. She does not defeat them with magic or martial arts; she simply stomps on them repeatedly. The camera shakes violently. The sound is a loop of crunching celery (meant to simulate exoskeleton fracture). Speculation continues
