In the middle of the Atacama Desert, a massive geometric pattern appears in the sand — perfectly formed, visible only from the sky, and gone by sunrise. No witnesses. No tracks. Just a single word embedded in the dust: UNSENT. A drone operator vanishes for a day. A signal whispers timecodes. And across Chile, the ground starts to hum.

The message was never sent.
But something is still listening.

Borderline Realities is a narrative podcast that investigates the thin, flickering edge between truth and the unbelievable in Latin America.
From hidden military experiments to unexplained disappearances, secret frequencies to forbidden files, each episode reveals a true case that feels too strange to be real — and too detailed to be made up.

If it wasn’t caught on tape… it might have been erased.

The Signal in the Sand

During routine construction under Bogotá, workers break through a sealed door and find something unexpected: a cold, silent room filled with reel-to-reel recorders and files labeled “MONITOR.” Each folder contains names, dates—and recordings of people who never knew they were being watched.

One tape plays the sound of a man sleeping.
The same man who finds it.
Ten years after it was made.

Silent. Unharmed. Untraceable.
In 2021, unaccompanied children began appearing at the U.S.-Mexico border — with no names, no history, and no biometric match. Some wore outdated hospital tags. Others carried coordinates that didn’t exist. They vanished from official systems. And one agent swears he saw the same girl three years apart — unchanged.

They weren’t trying to cross the border.
They were passing through.

The Children from Nowhere

In 2019, a nationwide blackout left Venezuela in darkness for seven days. Officials blamed cyberattacks. But deep inside the Guri hydroelectric plant, motion sensors detected someone in a control room sealed since 1998. No ID. No entry logs. Just a folder listing 47 substations — each marked "OFFLINE." Hours later, they were.

One photo survived.
And the badge on his chest belonged to a company that no longer exists.
