Before the Night portrays ordinary life under the enduring state of emergency, from the perspective of its three characters. Gulbîn, a painter living with her parents, is trying to make her own way in life, while obsessively painting a portrait of her mum with inspiration from Whistler's painting Mother. The mother models for her daughter while trying to insulate her house from the noise of the bombs to no avail. The father, whose health is deteriorating, tries to reimagine his war-stricken city with old photographs he took.

Osman can understand his mother tongue, Kurdish, but cannot speak it, and he speaks Turkish, which happens to be his second language, but cannot understand it. As a result of this condition of his, Osman starts to fail at handling two concurrent tasks. Just like he cannot respond to his patrons while he is working, he cannot engage in a conversation with his friends whilst they are having coffee together. Even though he wants to get married, he fails at sustaining a long-term relationship with women whom he meets. Osman’s life starts to change after a customer tells him that she could help him with his obsession.
