Peg O’ My Heart

Dr. Man, a psychiatrist, is plagued by recurring nightmares of a woman screaming behind a half-closed door. These visions invade his sleep and begin to spill into his waking life, eroding his focus and judgment at work. The persistent nocturnal terror sets the tone for his fragile mental state.

Man participates in a Hospital Authority hearing that allows him to privately investigate patients' backgrounds, crossing privacy lines. The procedure draws sharp rebuke from the hospital director, who warns that this is the last time he will back his colleague. The mounting tension foreshadows the ethical gray zones Man will navigate.

One night after work, Man rides home in a taxi driven dangerously by Choi, who seems lethargic and distracted. Curious about Choi's sleep, Man asks him about his dreams, and Choi reveals years of sleeplessness fueled by nightmares. Man offers a therapy card, but Choi discards it, signaling a growing barrier between them.

Choi's drowsiness causes him to drive the wrong way in a tunnel, triggering a serious crash and his subsequent arrest. The incident underscores his deteriorating mental state and becomes the catalyst for his psychiatric evaluation. The event anchors the medical investigation that follows.

During his evaluation, Choi is guided by Man to discuss his dreams. Choi describes being pursued by ghosts and mentions a buzzing fly, breaking down emotionally as he fears his wife Fiona's death. The session ends with Choi being taken back into custody, overwhelmed by memories.

After the session, Man meets Dr. Ching, a former psychiatrist who claims the ability to enter people’s dreams. Man remains skeptical, but Ching suggests that facing his nightmares directly could help him find freedom from them. The two debate the ethics and limits of dream intervention.

Man administers a sedative to Choi to induce sleep and considers electroconvulsive therapy as a way to end the nightmare cycle. Despite the attempt, Choi continues to dream of being chased, leaving him terrified and biting a tooth off in fear. The episode deepens the sense that sleep is not a simple solution.

Donna helps Man pull a background check on Choi and his wife Fiona, probing into a troubled history. Man visits Fiona's disheveled home, adorned with feng shui items, where Fiona appears unstable and briefly invites him in before begging him to leave them alone. He flees, unsettled by what he witnesses.

Man learns that Choi was a talented financial analyst who lost a friend's money during the 2008 financial crisis, which set his life on a downward spiral. A surveillance video from Choi's last day shows him modifying a document, revealing a betrayal that led to the friend's bankruptcy and suicide with his family. The revelation reframes Choi's guilt and intensifies his nightmares.

In the next session, Man pieces together that Choi is not merely guilty for losing money, but for betraying his friend. The memory of the altered contract and the friend's ruin surfaces through their dialogue, deepening Choi's emotional burden. Choi confronts his guilt as his nightmares intensify.

Choi recalls visiting his friend's burned-down house, where corpses lie surrounded by flies and a photo bearing a revenge note appears. The haunting image fuels his nightmares and triggers a tearful apology to his friend. Man reinforces that relief comes only through admitting guilt.

Man confronts his estranged father to uncover the origin of his nightmares: brutal beatings of his mother over money that drove her to jump to her death. His father apologizes for the abuse, and the two reconcile, offering Man a sense of personal closure. The confrontation shifts his burden from clinical work to family history.

Meanwhile, Choi, now imprisoned for fraud, is visited by Fiona. Despite his reassurance, Fiona cannot cope with their separation and takes her own life. The tragedy adds another layer of guilt to Man and Choi's intertwined fates.

In the mid-credits scene, Dr. Ching locks himself in a hotel room and enters Man's nightmare, revealing that Man has altered his own dream. He shows that Man's dream framed him as pushing his mother from the building. The twist deepens the film's meditation on guilt, memory, and the fragile boundary between dream and reality.
