Middle-aged Fredrik Egerman brings his 18-year-old bride Anne to a play starring his former mistress, Desirée Armfeldt. Soon, Fredrik and Desirée resume their romance, incurring the wrath of her current lover, a pompous Count. The situation culminates in a weekend at a country estate, with Fredrik, Anne, Desirée and the Count in attendance, as well as Fredrik’s son (who is hopelessly in love with Anne), Desirée’s illegitimate daughter, the Count’s manic-depressive wife and the Egerman’s lusty maid. And there, under the summer night, things are set to right.
