The rapidly growing global phenomenon of urban exploration (also known as Urbex or UE), in which thrill-seeking enthusiasts explore the normally unseen or off-limits areas of towns, cities and industrial facilities, provides the unique background for director Andy Fetscher's survival-horror shocker, Urban Explorers, which is coming to DVD and Blu-ray in March from Anchor Bay.

Looking for something different away from the usual well-beaten tourist trails of metropolitan Berlin, four young people – partners Denis (Nick Eversman) and Lucia (Nathalie Kelley), plus recently acquainted Marie (Catherine de Lean) and Juna (Brenda Koo) – hire local guide Kris (Max Riemelt) to take them on a tour with a guaranteed surprise. Kris leads the group into the city's dark and dank subterranean maze of wartime escape tunnels and underground fortifications on a rare, and illegal, trip to visit the legendary, graffiti-laden and now walled-up Nazi war rooms rarely seen by anyone since the end of World War II.

The trip takes an initial bad turn when the group encounters a pair of confrontational neo-Nazis and their dogs prowling around, but things get much worse when an unfortunate accident leaves Kris immobile and desperately in need of medical attention. Marie and Juna set off to find help, leaving Denis and Lucia to stay behind and look after Kris. The unexpected arrival of a bedraggled looking man, Armin (Klaus Stiglmeier), provides a ray of hope. A former East German border guard and now a self-appointed “guardian” of the tunnels, Armin takes them to his base with the promise of safety and a phone call for help. However, it soon becomes apparent that Denis and Lucia have just made the biggest mistake of their young lives.

The winner of the Best Picture, Best Actor (Klaus Stiglmeier), Best Editing and Best Make-Up awards at LA's prestigious Screamfest Horror Film Festival in 2011, Urban Explorers (which is also known under its singular as Urban Explorer) was decribed by Deread central as "a stunningly nihilistic piece of work delivered on a wave of shocking brutality and unremitting bleakness." Holy crap. It might cheer you to know that Variety called it, "a balance of craft and patience in building layers of suspense under a horrific setting that goes beyond any urban explorer's worst nightmare." Cool.

Urban Explorers will be released on UK DVD and Blu-ray by Anchor Bay Entertainment on 5th March 2012 at the RRP of £15.99 for the DVD and £19.99 for the Blu-ray.
