Heart of the Stag (1984)

Set against New Zealand's North Island scenery, this uneven but well-acted story is about Cathy (Mary Regan) -- a woman trapped in an incestual relationship with her father (Terence Cooper) on a remote sheep farm -- and a drifter named Daley (Bruno Lawrence) who arrives there looking for work. Daley soon develops an interest in Cathy, who is aloof and remote, and he does not understand why. When he does realize what is wrong, he and Cathy make a crucial decision that is bound to end in violence.
