Four years on, the Sewol Ferry disaster remains a collective trauma left deep inside the minds of many. Although most people have by now gone back to their daily lives, there are those who still find it difficult to recover from it – the bereaved families of the victims, the survivors and the divers who retrieved the bodies of the victims. Log Book is a record of the four years following the tragedy that the civilian divers have gone through. Through the on-site footage shot over 70 days, the divers’ logbooks and interviews with 15 civilian divers, the film tells the story of those who suffer precisely because of what everyone insists we must remember. They were the first to discover the victims and witnessed death at close hand. But is that the only reason why they can’t escape from the prison of memories? Just like the bereaved families of the Sewol disaster victims, perhaps they too suffer for a long time because of the insensitivity, incompetence and irresponsibility of the system? Log Book reminds us of a question that should never be forgotten. [BYUN Sungchan]
