A young woman arrives at her grandmother's house, which used to be a funeral home, to help her turn the place into a bed-and-breakfast inn. After they open, however, guests begin disappearing or turning up dead.

An old funeral parlor now converted into a tourist home during certain periods such as the summer, develops a problem, when a escaped mental patient with a split personality moves in and proceeds to do away with those specific/certain guests or staff, he/she feels are nosy or immoral.—????

At the beginning of the summer, Heather arrives in a small town called Northampton, to stay with her eccentric and religious grandmother, Maude Chalmers, whose house-a former funeral home-has recently been converted into an inn. Maude's husband, James, an undertaker, has been missing for several years, and she has been forced to make a living selling artificial flower arrangements; she hopes to supplant her income by opening the home to traveling guests. Billy Hibbs, a mentally-challenged man, lives with Maude as the property handyman.

Nearby, a farmer named Sam reports an abandoned vehicle discovered on his property, which is traced to a missing real estate developer who had been surveying the area. At the inn on the evening of Heather's arrival, guests Harry Browning and his mistress Florie check in. When Maude realizes the couple are unmarried, she asks them to leave, but they refuse. That evening after having drinks, they drive to a local quarry recommended by Heather; while there, Maude's truck arrives, smashing the back of their car and pushing them into the water below, where they both drown. The same night, Heather goes on a date with Rick, a local teenager, and returns home to hear her Maude speaking to an unseen man in the basement. When she inquires, Maude denies it.

The next day, while Maude is in town, Rick stops by the house. He tells Heather that her grandfather, James, was a known alcoholic, and recounts a story from his childhood in which Mr. Chalmers had locked him and a friend in the funeral home's basement to scare them. The two explore the property while Maude is gone; in the garage, they discover Mr. Chalmer's Cadillac hearse, and Heather finds a necklace with the initials "H.D." engraved on it. That evening, Heather again hears Maude speaking to someone in the basement, this time arguing with a male voice about a woman named "Helena Davis." Heather discovers Helena has been missing for some time, and was rumored to have eloped with her grandfather. Mr. Davis, Helena's husband, arrives at the house to ask Maude about the alleged affair, which she denies ever occurred. Later that evening, Mr. Davis is murdered with a pickaxe.

The following day while Heather and Rick are swimming in the quarry, Florie and Harry's bodies are discovered. Heather confides in Rick that she believes her grandmother is hiding someone in the basement. That evening, they return to the house. Upon finding that Maude is not home, the two decide to explore the basement. There they discover Billy's corpse, and are attacked by Maude, who, imitating her husband's voice, scolds Heather for coming into the basement. Maude attempts to kill Heather with an axe and she flees through the basement, discovering a hidden room where James's corpse rests in a bed of Maude's artificial flowers. Just as Maude is about to strike Heather with the axe, she lapses out of her dissociative identity. The police arrive at the scene in the basement, and Joe, a local police officer, asks Maude if they can talk about what has occurred. She agrees, so long as she can prepare a cup of tea.

Later, Joe explains to a news reporter that Maude had murdered James and Helena, his mistress, after discovering their affair. After, she preserved James's corpse, and buried both Helena and Mr. Davis in the local graveyard.
