As the year 1907 unfolds in a picturesque Swedish town, the Ekdahl family's well-established theatre is filled with a sense of nostalgia and peace. During the festive season, Alexander and his sister Fanny, revel in a Nativity play and an extravagant Christmas party surrounded by family and friends. Yet, unbeknownst to them, a profound change is on the horizon. The sudden death of Oscar Ekdahl, Emilie's husband, leaves her devastated, and her impulsive remarriage to the local bishop, Edvard Vergérus, begins a tumultuous chapter that disrupts their once-harmonious household.
Edvard's stern authoritarianism, which had seemed innocuous at first, soon darkens as he enforces rigid rules, particularly aimed at Alexander. Feeling the weight of his oppressive measures, Alexander struggles against the isolation and turmoil brought on by Edvard's presence. Emilie grows increasingly aware that her longing for freedom is fraught with difficulties, as divorce would mean losing her children to Edvard's custody under the law.
Seeking solace, Emilie confides in her former mother-in-law, Helena, sharing her secret about being pregnant, adding yet another layer of complexity to her already strained situation. Tensions rise as Edvard restricts Alexander and Fanny to their bedroom for what he claims is their safety. Within these confining walls, Alexander’s imagination spirals into stories of ghostly figures, reflecting Edvard’s darker past. Reports from Justina, the loyal maid, inadvertently launch a cycle of retribution and fear.
The narrative shifts dramatically when Emilie returns and, with the aid of their dear friend Isak Jacobi, orchestrates a daring escape for her children. They temporarily find refuge with Isak and his nephews, while Emilie's brothers-in-law strategize to confront Edvard and negotiate her freedom, wielding every advantage to better the children's circumstances. Despite their efforts, Edvard remains resolute, mirroring the harshness of the winter outside.
As Emilie's pregnancy reaches its peak, she cleverly uses a potent sedative to incapacitate Edvard, planning to leave him in a vulnerable state and abscond with their children. In a moment of dark irony, she prepares to abandon the household, hoping for a brighter future, but Edvard warns that her departure will bring dire consequences for her family. Unaware of the impact of the sedative, his threats fade as sleep takes over.
Amid this chaos, Aunt Elsa ignites a fire in the house, panicking and seeking Edvard's help. In a tragic twist, his efforts to extinguish the flames lead him to suffer critical burns which turn fatal. The family’s anguish deepens as they gather to celebrate the births of Emilie's child and another unexpected arrival involving Gustav Adolf and Maj, the maid.
In the midst of this familial turmoil, Alexander encounters the spectral figure of his stepfather, who hauntingly proclaims, > "You will never be free." Inheriting the theatre from her late husband, Emilie gifts Helena a copy of August Strindberg's A Dream Play, suggesting they perform it together. Initially skeptical, Helena finds herself drawn into this enchanting world, reading the play aloud to a slumbering Alexander, casting a spell that promises to weave their fates into something extraordinary amidst the darkness that surrounds them.
