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