Where can I watch Dear Thomas in Poland?

Thomas Brasch was born as a German-Jewish emigrant in England in order to move to the young GDR with his family at the beginning of the 1950s. His father Horst is primarily interested in helping to build the new German state. But Thomas prefers to realize himself as a writer and in doing so discovers his potential as a poetic rebel. His very first play was banned and soon afterwards he lost his place at the film school. When the tanks of the Soviet Union roll through the Czech capital Prague in 1968, Brasch and his girlfriend Sanda and other students try to call for protest in the streets of Berlin - and fail. His own father betrays him to the Stasi and allows Thomas to go to prison. After being paroled, he continues to try his hand at poet writing about love, revolt and death. In the GDR, however, you don't want to have anything to do with someone like him.
