Secret Office

A group of friends sets out on a hiking trip and stumbles upon a hidden tunnel deep in the woods. Driven by curiosity, they venture inside, expecting nothing more than a quick exploration. But as they go farther, the tunnel stretches endlessly beneath the earth, swallowing the light behind them.

When they finally decide to turn back, they realize the entrance is nowhere to be found. Darkness closes in around them, the air grows colder, and strange sounds begin echoing through the passageways. Trapped with no clear way out, the friends soon discover that the tunnel is hiding something far more terrifying than they ever imagined - and escaping it may already be impossible.
