On March 13, the detective or birthday of Alice, who has just returned from a two-year trip, gathers her old friends in her apartment. The party seems predictable until a bloody necklace is found among the gifts. Attempts to understand who sent it and to whom it is intended show that faithful wives, respectable housewives and quiet family keepers are not so sinless, and a brutal crime may be hidden in the past of each of them. Based on the play by Vlada Olkhovska.
