Oghi, a geography professor, survives a car crash that kills his wife but is left almost completely paralysed and unable to speak. She gradually dismisses his aide, turns away visitors, reads her dead daughter's private notes, and begins digging a large hole in the garden the daughter once tended, while Oghi lies in bed unable to ask what it is for.
When one person is wholly dependent on another for food, movement and contact with the outside world, every act of care is also an exercise of power: the caregiver decides who enters, what is heard, and whether needs are met. Because the arrangement looks like devotion from outside, withdrawal, isolation or punishment can be carried out inside it without anyone intervening.
In doing so he gradually exposes how he ignored his wife's frustrated ambitions, loneliness and resentment while pursuing his own career. Enforced stillness works as an involuntary audit: the self-flattering story a person tells about his relationships comes apart once he can no longer outrun it with busyness.
The hole could be a gardening project, a memorial or a grave, and the helpless observer cannot find out which. For someone with no ability to act or ask, an unexplained action by the person controlling them is worse than a known threat, because every possible meaning must be treated as real. Dread grows from the gap between what one can see and what one is allowed to know.
