A recluse observes increasingly disturbing activities in her apartment corridor through the peephole in her door, till finally she ventures out for a closer look.
A young woman's hermit-like existence is supplemented by endless hours spent viewing the comings and goings of others through the peephole in her apartment door.
Life passes uneventfully, but soon the activities within her 120 degree fish-eye viewpoint become increasingly disturbing, and not only because some passersby seem to have become aware that she's watching them.
Finally, late one night, when all is dark and quiet, the woman's curiosity gets the better of her and she ventures forth.
