Stray explores what it means to live as a being without status or security, following three strays as they embark on inconspicuous journeys through Turkish society. Zeytin, fiercely independent, embarks on adventures through the city at night; Nazar, nurturing and protective, easily befriends the humans around her; while Kartal, a shy puppy living on the outskirts of a construction site, finds companions in the security guards who care for her. The strays' disparate lives intersect when they each form intimate bonds with a group of young Syrians with whom they share the streets.
