1897. Oscar Wilde has just been released from prison after serving his sentence for gross indecency. Separated from his wife and children, he arrives in Dieppe, where old friends Reggie Turner and Robert Ross await him. Wilde assumes the alias of Sebastian Melmoth and tries to rebuild his life: he vainly writes to his wife Constance Lloyd to try to make peace with her. He is recognised by some young Englishmen, who taunt him and pursue him into a church; he defends himself violently, then receives severe warnings from the police.

Oscar then reunites with his old lover Bosie Douglas, angering Robbie, whose secret love for him has never been reciprocated. Oscar and Bosie flee together to Naples, where they live for some time in a house in Posillipo, leading a libertine life. Soon Bosie's mother ceases to send her son his allowance – she is willing to resume payments and give a £200 payoff to Oscar if the two lovers separate. Despite Oscar's anger, they give in and separate. Shortly afterwards Constance, who had forbidden Oscar any contact with Bosie, dies from complications following surgery, and Oscar is denied any contact with their two children.

Now incapable of writing, Oscar takes refuge in Paris, where he lives off his wits and the charity of his old supporters. He meets Reggie and Robbie again and shortly thereafter he finds Bosie, who recently received a large inheritance on the death of his father; Bosie angrily refuses to help him. Meanwhile, the writer begins to show strange symptoms that he attributes to mussel poisoning, suspecting however that it may be syphilis. He meets two poor brothers with whom he shares misery: the elder becomes his favourite, while the younger wants to hear the fairy tale The Happy Prince, which the writer always told his children.

Oscar's illness worsens and he receives a painful surgical operation to treat an abscess in his ear. His precarious physical state causes post-operative infections. With his last strength Oscar asks for an extreme Catholic unction, only to die surrounded by the few friends he has left. At the funeral Robbie complains to Bosie that he was a hypocrite, because he mourns the death of the man who had always loved him and whom he had abandoned without showing any gratitude. Bosie replies that these words are dictated by jealousy, and that only he will be remembered alongside Oscar Wilde, while Robbie will be forgotten.

The film's closing headlines state that Bosie died alone and penniless in 1945, while Robbie, who died in 1918, was buried in Oscar's own grave. Oscar was pardoned in 2017 together with other people convicted of homosexual offences.
