PRE-ORDER THE BOOK
Shipping of the book will start at the end of June. The film is expected in July.
Deep beneath Sofia lies a heavily surveilled network of tunnels, bunkers, and Soviet-era subway stations - largely unseen, rarely photographed, and almost impossible to access.
THE BOOK
A rare and audacious act of documentation. Over almost a decade, anonymous photographer Errorflict and his steadfast accomplice Seco slipped past guards, outsmarted surveillance, and navigated Sofia’s heavily secured, Soviet-era subway system, turning an untouchable fortress into a visual archive.
This 296-page photo book blends cinematic photography with wild tales of escape, loss, and triumph. It reveals the stark, surreal, and strangely intimate beauty of a city’s unseen heart, where few have dared to go and even fewer have managed to return with proof.

THE FILM
Is the emotional core behind the archive. Told through the voice of Errorflict himself, it explores why this project mattered so much and what it cost. It’s not just about breaking into tunnels, but breaking through fear, addiction, and obsession. The film is intimate, chaotic, and reflective - where the underground becomes a metaphor for mental states, memory, and identity.
Film Synopsis
Hidden beneath Sofia, Bulgaria, lies one of the most impenetrable and heavily guarded metro systems in the world. Untouched, unseen, and unexplored.
Until now.
Sofia Metro Inside Out is the untold story of Errorflict, an anonymous urban explorer turned visual archivist, who spent nearly a decade slipping past security systems, outsmarting sensors, and navigating Soviet-era infrastructure that was never meant to be photographed - let alone filmed.
What begins as a dare to explore quickly spirals into obsession. From rusting tunnels and forgotten bunkers to train yards humming with danger, Error and his accomplice Seco go deeper and deeper, transforming the metro into both playground and battlefield. Along the way, they blend graffiti culture with urban infiltration, breaking into places designed to break them.
But this is more than a documentation of graffiti and urbex.
It's a confession.
Told entirely in Error’s own words, the film evolves into a raw inner journey - a story of escape, loss, adrenaline, and addiction. As the thrill fades and the risks multiply, the camera turns inward. What’s left isn’t just an archive of a vanishing world, but a self-portrait of a man caught between memory and release.
Equal parts cinematic documentary and emotional diary, Sofia Metro Inside Out offers never-before-seen access to one of the most fortified subway systems on Earth - while quietly revealing something even more rare: what it means to chase freedom, and what it costs to finally let go.
