Love Me Deadly is a 1972 American horror film directed by Jacques Lacerte and starring Mary Charlotte Wilcox, Lyle Waggoner, and Christopher Stone.
The screenplay concerns a coven of devil-worshipping necrophiles that moves to Los Angeles and sets up their base of operations out of a funeral home.
Young, attractive Los Angeles heiress Lindsay Finch has a habit of dressing in mourning and attending wakes for men she never knew.
Meanwhile, mortician Fred McSweeney notices Lindsay's attendance at the wakes and, although she won't admit to her secret passion, he recognizes her as a kindred spirit.
When Wade follows her to the funeral home, he stumbles across one of the group preparing a body for the coming orgy, and is killed before being sexually ravaged by the cult.
The two get married, but Lindsay can't bring herself to consummate the marriage, and Alex is confused and frustrated by his new wife's inability to return his affections.
Before leaving, Alex opens a registered letter addressed to Lindsay from Fred's funeral parlor, notifying of a meeting that night.
