"Brideshead Revisited" tells an evocative story of forbidden love and the loss of innocence set in the pre-WWII era. In the film, Charles Ryder becomes entranced with the noble Marchmain family, first through the charming and provocative Sebastian Flyte, and then his sophisticated sister, Julia. The rise and fall of Charles' infatuations reflect the decline of a decadent era in England between the wars.
