What Is Sister Cupid About?
The premise of Sister Cupid in 312 words, with nothing given away. The full story follows below.
In a bustling Hong Kong neighborhood where neon lights flicker over narrow alleys, everyday life carries an undercurrent of the uncanny. The film follows Kit, a carefree young man whose routine is shattered when a sudden loss of control on his motorbike sends him crashing into a modest house. There, an enigmatic girl appears out of nowhere, swoops in to pull him from danger, and then vanishes as mysteriously as she arrived, leaving a lingering sense that the ordinary world may be brushed by something otherworldly.
Soon after, the rhythm of Kit’s life becomes a delicate dance of attraction and intrigue. His newly‑settled neighbor, a confident woman with a warm smile, begins to show a keen interest in him, while her sister Dodo, who shares a close bond with her, inevitably gets pulled into the growing circle of affection. The atmosphere thickens with subtle humor and quiet yearning, as each character navigates the fine line between friendship and romance amid the city’s lively backdrop of cafés, night‑clubs, and the occasional ghost‑laden legend that locals whisper about.
The story also glimpses the deeper familial ties that shape the lives of those around Kit. Yu‑yee, a determined nightclub madame, and her brother Kat‑cheung—the same Kit’s older sibling—share a history marked by loss and loyalty, their bond echoing through the streets and into the lives of the younger generation. Meanwhile, a charismatic figure known only as Big Sister presides over an annual gathering that hints at lingering memories of a long‑gone daughter, adding a bittersweet note to the urban tapestry.
Against this vibrant, slightly surreal setting, Kit finds himself caught in a web of competing affections and unresolved feelings. The film balances light‑hearted romance with a subtle eerie undertone, inviting the audience to wonder how much of what we see is guided by chance and how much is steered by forces just beyond our perception.

Kam Yu-yee Carol Cheng and Kam Kat-cheung Jacky Cheung are siblings who were orphaned at a young age and have depended on one another ever since. Yu-yee, a nightclub madame, is deeply devoted to her brother and supports him, even though she has never approved of his girlfriend, Jackie. To strike back at Yu-yee, Jackie arranges for Kat-cheung to elope, but the plan goes awry when a traffic accident sends them careening down a mountain slope. Kat-cheung is rescued by a dead spirit who has lingered for two decades. With Jackie’s scheme foiled, she moves next door and summons her cousin Benjamin Natalis Chan Pak-Cheung to retaliate against Yu-yee, much to Kat-cheung’s annoyance. Meanwhile, Yu-yee also pursues a career breakthrough and works to please her boss, Big Sister Tang Pik-Wan. Big Sister dearly misses her only daughter Yuk, who drowned twenty years ago and holds a yearly dance party to remember her; Yuk Maggie Cheung is the daughter who haunts the memory of the household. To help with the ghostly plan, Yu-yee suggests organizing a ghost marriage for Yuk, and she is tasked with finding a ghost son-in-law for Big Sister. As the deadline approaches, Yu-yee supplies Kat-cheung’s birthday, the eight characters of his horoscope, and a jar of peanut powder posing as bone ashes to Big Sister. On the night of the wedding, Kat-cheung, who has gotten drunk at Big Sister’s mansion, sees Yuk in a wedding dress and experiences a sense of déjà vu, as if he has met Yuk before; the moment ends with them spending the night together.
