A weary office worker, drained by the demands of a black company, finds his monotonous life taking an unexpected turn. One day, mistaking a plastic bag caught on a utility pole for a cat, he leans over his balcony to investigate. His concerned neighbor, misinterpreting his actions as a suicide attempt, intervenes dramatically. Upon regaining consciousness, he discovers he's been bound and confined in her apartment. The neighbor, exhibiting obsessive affection, declares, "You're safe now... I'll take care of you forever." Thus begins a twisted tale of captivity, where the lines between protection and possession blur.
