A Russian drama/mystery movie from the 2000s where three men and a woman make a trip to a secret place in the middle of nowhere , where they will find a church and go to heaven from there, i think. The protagonist is this tall guy with a hunchback, he's got blonde semi-long hair and he plays guitar. At the start he meets his friend and they go get their other friend from an hospital, where they beat up the nurses to take him and get him out. They pick up the woman on the road, as she was hitchhiking.Also at some point the woman is forbidden to enter a militarized zone if she doesn't strip naked.

If anyone thinks they know what i'm talking about please tell me!
