In the movie, Lilith (Shiri Appleby) and William Shaw (Richard Burgi) join forces to kill the Demonicus, an evil beast that is starting a worldwide plague.
[1][2][3] Lilith is introduced as Elle, a young woman who lives with a guardian.
God turned her into an immortal demoness who kills the children of Adam and Eve.
When the ambitious yet evil scientist Anders Raeborne (David Hewlett) used an extract from Lilith's blood in an attempt to become immortal, he became the evil Demonicus, a powerful monster who transmitted a red plague with his bite and tongue.
The leaders of Faith, The Prefect (Ross Manarchy) and Chapel (John de Lancie), assigned Chief Agent William Shaw to help Lilith regain her memories and train her to destroy Demonicus and bring his head to develop an antidote.
