Wealthy American Jew Jeremiah Mendelstrum decides to donate funds for the construction of a ritual bathhouse - mikva - in memory of his deceased wife in the City of the Righteous in the Holy Land. A suitable place is located only in an area inhabited by repatriates from Russia who do not know what a mikva is, and sincerely believe that the municipality is building a chess club for them... In the most incredible way, the bathing club will change the fate of many of its visitors.
