What Is Five Dolls for an August Moon About?

The premise of Five Dolls for an August Moon in 346 words, with nothing given away. The full story follows below.

A remote island retreats from the world, its lone beach house perched against a backdrop of surf‑lapped cliffs and whispering palms. It belongs to a charismatic industrialist who has gathered his most privileged acquaintances for a weekend that promises sun, luxury, and an escape from the constraints of city life. The isolation feels both intoxicating and unsettling, a place where the ordinary rhythm of society is replaced by the slow pulse of endless horizon and the quiet hum of distant waves.

George Stark is the host, a wealthy playboy whose effortless charm masks a shrewd business mind. He has invited a colorful cast: Professor Gerry Farrell, a brilliant scientist protecting the secret of a revolutionary resin formula; his wife Trudy, whose restless spirit hints at hidden desires; Jill, Stark’s artist wife, whose creative ambitions are tightly intertwined with her husband’s ambitions. The circle also includes Nick, Stark’s partner whose volatile relationship with his wife Marie cracks the veneer of upper‑class civility, and Charles, the devoted manservant who moves silently among the guests. Jack and his companion Peggy appear as the seemingly contented couple, while Isabel, the young daughter of the island’s game warden, watches the adults with a keen, observant eye. Beneath the polished surface, alliances shift, old resentments simmer, and unspoken attractions create a web of tension that feels as palpable as the salty air.

The weekend quickly becomes a pressure cooker of ambitions and secrets. Farrell’s guarded invention draws relentless attention, and each guest arrives with their own agenda—whether it’s securing a lucrative deal, escaping personal constraints, or simply enjoying the rare freedom the island affords. Conversations glide between polite flirtation and veiled challenges, while the ever‑present ocean seems to echo the growing undercurrents of mistrust.

As night falls and the tide cuts off any easy escape, the atmosphere tightens into a lingering suspense. The sumptuous setting contrasts sharply with the mounting sense that something crucial is at stake, and that the very freedoms the guests seek may be lurking just beyond the horizon, waiting to test the limits of their loyalties and desires.

Spoilers ahead

On the private island retreat of the wealthy industrialist George Stark Teodoro Corrà, a weekend gathering brings together a mix of guests, including the renowned scientist Professor Gerry Farrell William Berger. The first night passes quietly, but the mood shifts when Farrell awakes to a startling realization: Stark and the others have set this weekend up to pressure him into selling his groundbreaking resin formula, a invention whose origin he guards closely after the death of a colleague during its creation.

Farrell’s world is tangled in personal conflict. His wife Trudy Ira von Fürstenberg is involved with Jill, Stark’s artist wife, while Stark’s business partner Nick Maurice Poli is openly abusive toward his wife Marie Edwige Fenech, yet shows little objection to her sleeping with other men, including Charles Mauro Bosco, the Stark household’s manservant. Stark himself treats Jill more as a means of enhancing his portfolio than as a partner, constantly steering her career and keeping tight control over every aspect of her life. The only truly contented couple appears to be Jack Howard Ross and Peggy Helena Ronee. Also present is Isabel Ely Galleani, the teenage daughter of Stark’s game warden, whose parents are away for medical reasons.

As the trio of Stark, Nick, and Jack press Farrell for the secret formula, they each try to seal the deal with conspicuously large cheques—$1 million apiece—from their Swiss accounts. The pressure mounts in the open air and the tension soon turns grim. Jill discovers the dead body of Charles on the beach, a grisly clue that someone on the island might be willing to go far to protect the prize they crave. With the motor launch already sent away to block any escape and the radio out of service, Charles’s body is moved into a large walk‑in freezer, a place that will later become a macabre locus for the day’s horrors. The next morning, Farrell is found on the beach, and the group learns in horror that he has been murdered; Isabel, the sharp-eyed sniper, drags Farrell’s body toward the sea as the situation spirals.

Tempers flare as the island devolves into a chain of killings. Peggy is shot dead from an unseen sniper, and Jack immediately accuses Stark of the killings. Marie is found bound to a tree and stabbed in the chest, while Jill is discovered dead in her bathtub, wrists slashed in what appears to be a staged suicide. Each corpse is disposed of in the freezer, turning the island into a chilling gallery of cadavers. The four survivors—Stark, Jack, Nick, and Trudy—hole up in Stark’s living room through the night, trading barbs and accusations as the danger closes in. After a heated exchange, Nick storms off, and the next morning he too is found dead, his body added to the growing cold-storage tableau.

Stark tries to salvage some chance of escape by offering Trudy a cheque for Farrell’s formula, while a microfilm reveals that the secret remains in existence. A hidden motorboat is unearthed, offering a path back to the mainland, but Stark’s attempt to gather supplies takes him away, leaving Jack to confront the truth: he orchestrated the murders to steal the cheques, including Peggy’s, and has now turned to lethal means to protect his plan. In a tense confrontation, Trudy agrees to deliver the formula in exchange for Jack’s cheque, and a dangerous handover ensues. Yet the exchange ends in tragedy as they both shoot each other; Trudy dies first, and Isabel seizes both the cheque and the formula, though a dying Jack makes a last, futile attempt to stop her.

Time passes, and Isabel—now wealthier than before—visits Farrell in prison, awaiting execution for the murder of his colleague, the rightful discoverer of the resin. She claims to love Farrell and confesses that she intended to save him by drugging him with a sodium pentathol pellet, a truth-serum style move that coerces him into confessing his guilt. Isabel reveals she is broke, having cashed George’s and Jack’s cheques but not Nick’s because she never learned the account number. Farrell, aware of his fate, provides her with the number before she departs for Lausanne, convinced she has altered the course of history on that distant island.

Themes

What Are the Themes of Five Dolls for an August Moon?

4 ideas the story keeps returning to, among them Greed, Betrayal and Deception.

  1. 01

    Greed

    Greed drives much of the film's conflict as the promise of a million-dollar payoff for Farrell's resin formula fuels scheming and coercive tactics. The guests promise or threaten money to secure the invention, revealing how wealth corrupts relationships and ethics. The pursuit of financial gain ultimately sharpens the violence and deception that unfold on the island.

  2. 02

    Betrayal

    Betrayal threads through marriages, partnerships, and friendships as loyalties shift under pressure. Characters hide true motives while exploiting others’ weaknesses, leading to a cascade of murders. The revelation of each betrayal escalates the mystery and shifts blame among the survivors. The island becomes a pressure cooker where trust is a currency as deadly as money.

  3. 03

    Deception

    Deception pervades every interaction, from illicit affairs to manipulation of legal documents and secret plans. The destruction of original documents and the use of a hidden microfilm show how truth is obscured to serve personal ends. Characters continually mislead others to preserve their own survival and wealth. The truth only surfaces amid a web of calculated lies.

  4. 04

    Mystery

    A concealed motive lurks behind each action as bodies begin to pile up and motives remain unclear. The film builds a layered puzzle, inviting viewers to piece together who benefits from each death. Clues are scattered through the island’s setting, the relationships between guests, and the shifting control of the resin formula. The final twist reframes who truly controls the outcome and who is left with the fortune.
