Their lives are ostensibly idyllic, but each couple bears its own sordid secrets; Ali and Laleh have a strained relationship after the purchase of an apartment, while Bahram and Tamineh have their own financial concerns. As the party progresses, cracks begin to appear, and accusations fly. Host Yassi, meanwhile, struggles under the weight of the group’s pressure. A gripping drama that unfolds almost entirely in real time that focuses on relationships, deceit and trust.
