Set largely in the dark atmospheric backwoods just outside of New Orleans, The Skeleton Key stars Hudson as Caroline, a live-in nurse hired to care for an elderly woman’s (Rowlands) ailing husband (Hurt) in their home…a foreboding and decrepit mansion in the Louisiana delta. Intrigued by the enigmatic couple, their mysterious and secretive ways and their rambling house, Caroline beings to explore the old mansion. Armed with a skeleton key that unlocks every door, she discovers a hidden attic room that holds a deadly and terrifying secret. Peter Sarsgaard portrays Luke, the local attorney working on the couple’s estate, and Joy Bryant plays Jill, Caroline’s best friend.
