Simin (Leila Hatami) and Nader (Peyman Moaadi) are a middle-class couple whose 14-year marriage has hit the rocks over what's best for their bright 11-year-old daughter Termeh (Sarina Farhadi).
Simin wants them to emigrate to somewhere that gives women greater opportunities, while Nader refuses to countenance that idea, not least because he needs to stay in Tehran to care for his ageing father (Ali-Asghar Shahbazi), who suffers from Alzheimer's.
The clash leads them to the divorce court and a subsequent separation. The latter results in a poor working-class woman called Razieh (Sareh Bayat) being hired to look after the old man while Nader is at work.
But far from providing a solution, her introduction will, through a domino-effect of unintended consequences, prove disastrous.
In addition to the compelling narrative, writer-director Asghar Farhadi's film offers, through its various characters, intriguing views of class, gender and religion in modern Iran.
As well as picking up the Best Foreign Language Academy Award, the movie also won scores of other awards around the globe.
