With the return of their friend Ahmad from Germany, a group of old college pals (two married couples and a brother and sister, along with three young kids) decide to reunite for a weekend outing by the Caspian Sea. The fun starts right away as they quickly catch on to the plan of lively Sepideh, who has brought along Elly, her daughter's kindergarten teacher, in hopes of setting her up with recently divorced Ahmad. But seemingly trivial lies, which start accumulating from the moment the group arrives at the seashore, suddenly swing round and come back full force when one afternoon Elly suddenly vanishes. Her mysterious disappearance sets in motion a series of deceptions and revelations that threaten to shatter everything they hold dear.
