Jessica Brown Findlay (Downton Abbey's Lady Sybil) is Mary Yellan, the heroine of Daphne du Maurier's gothic coming-of-age tale set in 1820s Cornwall. Forced to live with her violent uncle after her mother dies, Mary finds herself among a band of sadistic smugglers in a lawless, windswept land. No one is quite who he seems--including the handsome, untamable Jem Merlyn (Matthew McNulty, The Paradise), the man she loves. From the BBC. 3 episodes, 3 hrs, 1 DVD, SDH.
