Post World War II, a British colonel and his wife are assigned to live in Hamburg during the post-war reconstruction, but tensions arise with the German who previously owned the house.

Copenhagen, 1926. Danish artist, Gerda Wegener, painted her own husband, Einar Wegener (Eddie Redmayne), as a lady in her painting. When the painting gained popularity, Einar started to change his appearance into a female appearance and named himself Lili Elbe. With his feminism passion and Gerda's support, Einar - or Elbe - attempted one of the first male-to-female sex reassignment surgery, a decision that turned into a massive change for their marriage, that Gerda realized her own husband is no longer a man or the person she married before. A childhood friend of Einar, art-dealer Hans Axgil (Matthias Schoenaerts), shows up and starts a complex love triangle with the couple.
