The Koker trilogy is a series of three films directed by acclaimed Iranian film-maker Abbas Kiarostami: Where Is the Friend's Home? (1987), Life, and Nothing More... (a.k.a. And Life Goes On, 1992) and Through the Olive Trees (1994). Where Is the Friend's Home? depicts the simple story of a young boy who travels from Koker to a neighbouring village to return the notebook of a schoolmate. Life and Nothing More follows a father and his young son as they drive from Tehran to Koker in search of the two young boys from Where Is the Friend's Home?, fearing that the two might have perished in the 1990 Iran earthquake that killed 50,000 people in northern Iran. Through the Olive Trees examines the making of a small scene from Life, forcing the viewer to witness a peripheral drama from Life as the central drama in Olive.
An 8-year-old boy must return his friend's notebook he took by mistake, lest his friend be punished by expulsion from school.
After the earthquake of Guilan, a film director and his son travel to the devastated area to search for the actors from the movie the director made there a few years previously. In their search, they see how people who have lost everything in the earthquake still have hope and try to live life to the fullest.
When the actor in a scene for his film Life And Nothing More… has to quit, a film director casts another man for the part. However, complications arise since the man and the woman who was cast for the scene know each other.
