The eponymous walls belong to a grey prison building – a symbol of cruel, yet fearful rule of President Lukashenko. Families of the detained are standing in front of the building, they are mostly women supporting political prisoners: their husbands, brothers and sons. Andrei Kutsila's film, produced by Belsat TV, provides us with an insight into emotions and the psychological condition of the Belarusian society. It also shows mechanisms of stifling resistance – one of them is depriving relatives of any information about the detained. Uncertainty and longing give rise to wrath.
