Portrait of a Marriage es la historia de la tempestuosa relación que unió a Vita Sackville-West y Violet Trefusis-Keppel. Está basada en un libro sobre Vita, escrito por Nigel Nicolson, hijo de Vita. En este se retrata la vida de Vita y sus amores, no sólo su relación con su esposo sino con otras mujeres que marcaron su vida tal como Violet Keppel (Trefusis), una historia que marcó su vida. Tras cinco años de matrimonio, Harold Nicholson le confiesa a Vita su homosexualidad. Irónicamente, al mismo tiempo, Violet, amiga de la infancia de Vita le confiesa que siempre la ha amado. Este es el comienzo de una relación apasionada, que las llevará a viajar fuera del pais. A pesar del amor que la impulsa hacia Violet, Vita pospone contarle la verdad a Harold. Mientras tanto, Violet decide casarse con Deny Trefusis, bajo la condición de no tener sexo, esto pone a Vita celosa y temerosa de perder a Violet. Así deciden reencontrarse y pasar sus vidas juntas, ambas se lo cuentan a sus respectivos esposos, pero cuando están de camino al sur de Francia, los hombres deciden seguirlas y traerlas de regreso al hogar. 

El propio hijo que es el autor de la novela describe de esta manera el amor de Vita por Violet: 

”I did not know Violet. I met her only twice, and by then she had become a galleon, no longer the pinnace of her youth, and I did not recognize in her sails the high wind which had swept my mother away (…). I did not know that Vita could love like this, had loved like this, because she would not speak of it to her son. Now that I know everything I love her more, as my father did, because she was tempted, because she was weak. She was a rebel, she was Julian [Vita’s travesty], and though she did not know it, she fought for more than Violet. She fought for the right to love, men and women, rejecting the conventions that marriage demands exclusive love, and that women should love only men, and men only women. For this she was prepared 
to give up everything. Yes, she may have been mad, as she later said, but it was a magnificent folly. She may have been cruel, but it was a cruelty on a heroic scale. How can I despise the violence of such passion?”
