Dementia 2015

While out for a late-night rowing expedition on a shimmering lake, John Haloran finds himself embroiled in a heated dispute with his wife, Louise. The couple’s argument centers around the contentious will of John’s affluent mother, which spells disappointment for Louise as she discovers that all assets are set to be donated to an enigmatic figure known only as “Kathleen.” This distressing revelation intensifies their quarrel and, amidst the physical exertion of rowing, John’s heart succumbs to a fatal attack. Stricken by grief, he informs his beloved that in the event of his death prior to their mother’s, she would forfeit any claim to the inheritance—a proclamation that seals his tragic fate as he takes his last breath. Faced with a grim situation, Louise makes the shocking decision to dispose of his lifeless body, casting it into the depths of the lake, as she concocts a deceitful plan to feign John’s existence to secure her future. With determination, she pens a deceptive letter to her mother-in-law, Lady Haloran, inviting herself to the family’s opulent castle in Ireland under the pretense of his “business trip.”

Upon her arrival at the grand castle, a blend of tension and eerie tradition envelops John’s two brothers, Billy and Richard, who are caught up in a peculiar yearly ceremony orchestrated by their mourning mother, Lady Haloran. This ritual serves as an annual tribute to their late sister, Kathleen, who tragically drowned in a freak accident. In a heavy atmosphere of remembrance, Lady Haloran visibly falters as she experiences a familiar fainting spell—an occurrence that has become customary each year as she mourns her lost daughter. As Louise aids her mother-in-law back into the castle, Lady Haloran confides her emotional distress, attributing her fainting to the wilting of the freshly scattered flowers that failed to honor Kathleen’s grave.

Recognizing Lady Haloran’s emotional fragility, Louise hatches an insidious plan to exploit her mother-in-law’s superstitions. She sneakily acquires some of Kathleen’s childhood toys and submerges them in the estate’s pond, intending for them to later resurface in a ghostly fashion. However, her chilling discovery of what seems to be Kathleen’s preserved corpse lurking at the pond’s bottom sends her into a panic. Before she can comprehend her horror, an unknown assailant assaults her with an axe, pulling her lifeless body from the scene.

The family’s concerns escalate as Dr. Justin Caleb, their trusted physician, arrives to unravel the unfolding mystery. His inquiries into the family’s dark events lead to grotesque discoveries, including the gruesome decapitation of a poacher named Simon on the estate. In a bid to uncover more secrets, Dr. Caleb drains the pond, unveiling a disturbing shrine engraved with the poignant words, “Forgive Me, Kathleen.” That fateful night, Lady Haloran is abruptly attacked by a shadowy figure, but in a narrow escape, she collapses in the castle’s courtyard, deep in fear.

Using the clues provided by a fragmented nursery rhyme—recited by a hypnotized Billy—Dr. Caleb’s relentless pursuit of the truth reveals Louise’s frozen body, concealed within the cold confines of a meat locker, accompanied by a macabre wax figure of Kathleen. In a bold attempt to lure out the malevolent force responsible for the chaos, Dr. Caleb places the disturbing figure in a public square—a daring ploy that results in a mad, guilt-ridden Billy attacking Richard’s fiancée, Kane, with an axe in a frenzied bid to eliminate the perceived threat. Dr. Caleb intervenes just in time, using his firearm to end Billy’s rampage, all while navigating the tangled web of guilt, grief, and supernatural retribution that has engulfed the Haloran family.
