The Wedding from Hell

A demonic bride-to-be (Jade D'Mon) that manifests every two hundred years to create a demonic offspring in a wealthy and influential human family suddenly replaces the human bride (Alison Michaels) a week before the wedding by having a magical contractual 'hold' over the grooms' mother (Grace Spencer) as well as by casting a spell over the groom (Elliot Spencer). A priest dedicated to fighting demonic influences, expecting the demon's cyclic manifestation, attempts to intervene with a dagger designed to defeat the demon and her group of allies now managing the estate. The Halliwell sisters gradually discover the strange events about the wedding, as Piper is catering the event. Meanwhile, Prue's work at the auction house is used by Andy, investigating the murder of the priest with the weird ancient dagger now found dead at the estate. The sisters confirm demonic involvement by spying the night before the wedding. They confront Alison and formulate a plan to desperately execute before the ceremony can be completed. Discovered before the vows, a battle ensues and the police, led by Andy and Darryl, arrive as the battle climaxes. Grace helps Alison and the Halliwell sisters, resulting in the defeat of the pack of demons and Jade so that Elliot and Alison are reconciled and united.
