A Surplus of Wind (Višak vjetra) 10 years old

Two men - one in the West, one in the East, brothers. In both places, life is muted, solitary, nondescript. Here, windows are painted, switches rewired and cigarettes smoked; there, lengths swum, boxing matches prepared for, transactions made. What is it that links these things? Winter swimming pools, the sound of a bell, a bullet passing through bone?
