The three daughters of Lilith roam the earth, stealing souls and leaving dead bodies in their travels. Leandra, the oldest, seeks to put her own soul to rest and finally ease the burdens of the lives she has taken over the centuries. But after a visit from a stranger, she finds that being a succubus may get her killed rather than have her to die a peaceful death.
