A middle-aged lawyer, Frederik Egerman (Gunnar Björnstrand), his inexperienced young wife, Anne (Ulla Jacobsson), and her step-son, Henrik (Björn Bjelfvenstam), are invited to spend the weekend at the country mansion of a beautiful actress, Frederik's ex-mistress, Desiree Armfeldt (Eva Dahlbeck). Amongst the guests are Desiree's current lover Count Malcolm (Jarl Kulle) and his wife Charlotte (Margit Carlqvist). During the course of the weekend these three couples meet, separate and exchange partners, providing some lively comedic action and illustrating. Bergman's sardonic attitude towards the vagaries of love. Behind the scintillating and witty approach to this charming period comedy of manners lie and illusions and pretensions of the haute bourgeois, which Bergman cleverly illustrates with his collection of fickle husbands and scheming women.
