Yousef manages a successful veterinary practice for cattle from a village in the vast Sari region of Iran, regularly visiting remote farms in the surrounding area. During a particularly harsh winter, hungry wolves attack a herd of cattle and Yousef is badly burned when a barn catches fire and he tries to save the cattle inside. This grim succession of events leaves him with an obsessive hatred for wolves that only starts to mellow when he meets a woman who is a keen environmentalist. Against this background, the immediate story revolves around the disappearance of Khorshid, the daughter of Yousef’s friend Khali. The villagers join forces to help search for her until a secret is revealed.
