The Bunker is a 2001 war horror film directed by Rob Green, written by Clive Dawson and starring Jason Flemyng.
Mirus relates the history of the area, where victims of the Black Plague were massacred on the orders of a stranger who influenced the townspeople to turn against one another.
Krupp asks Mirus to explain the mysterious activities but is interrupted by machine gun fire in the bunker.
When Heydrich, Baumann and Helmut Franke try to blow the bunker door with a stick grenade, Schenke and Neumann mistake the noise for an American assault.
The trio find the main exit blocked, try to escape through the mine shaft, and fire at an approaching figure.
Corporal Baumann gives Neumann permission to surrender to the Americans and he sets off, finding Mirus' body in the barbed wire.
The film cuts to a flashback in which Baumann's squad is marching through a field on a sunny day, coming upon a group of deserters about to be executed.
An officer delivers the coup de grace and the firing party pose for photographs with the executed man.
[1] AllMovie gave the film a mixed review stating, "The Bunker is an admirable horror outing that comes close to delivering the shocks, but ends up on the drab side of things when all is said and done".
