In September of 1892, Oscar Wilde and his family retreated to the idyllic Norfolk countryside for a holiday. His wife, Constance, has every reason to be happy: two beautiful sons, a stellar reputation as an advocate for progressive causes, and a delightfully charming and affectionate husband and father, who is perhaps the most famous man in England. But as an assortment of houseguests arrive, including an aristocratic young wannabe poet named Lord Alfred Douglas, Constance gradually - and then all at once - comes to see that her husband's heart is elsewhere and that the growing intensity between the two men threatens the whole foundation of their lives.
