The Riverbed (1986)

"The Riverbed traces the story of a despondent drifter who stumbles across a farmhouse inhabited by a wealthy widow and her disabled daughter. Exchanging board for labour, he stays at the house. Eventually he consents to the mother's wish that he marry the girl, with his eye on financial gain. He takes the girl to the city, where the couple struggles against hardship. As the man reverts to petty theft, her health deteriorates and he is forced to take her back to the now-abandoned farmhouse." - MIFF
