Presented in the first person, the story is a collection of journal entries written by a woman (Jane) whose physician husband (John) has confined her to the upstairs bedroom of a house he has rented for the summer. She is forbidden from working and has to hide her journal from him, so she can recuperate from what he calls a 'temporary nervous depression - a slight hysterical tendency,' a diagnosis common to women in that period. The windows of the room are barred, and there is a gate across the top of the stairs, allowing her husband to control her access to the rest of the house.
