Grace, a melancholic vampire, calls a suicide hotline asking for advice on how to die. She connects with Ness, the hotline worker who answers the phone, and poses the question of what is most safety in knowledge or certainty and excitement in death. The two women embark on a dangerous love story; the more Grace reveals about her life on the outskirts of society, the more Ness understands her desire to die. Ness agrees to help Grace find a way to end her existence, but she secretly hopes their connection will make Grace reconsider.
