Dead Calm (1989)

John and his wife locate a schooner in the middle of the sea during their navigation on a Dead Calm day. A raft reaches them, driven by a desperate man. All his shipmates died while eating spoiled food and he’s the only survivor, looking for help. In reality, man is a psychopath! Some days make you think that it was much better to stay in bed.
Nicole Kidman gives us a couple of nude sequences between one problem and another. A beautiful sex scene under deck and her ass on the deck of the ship.
