As Alice Kingsleigh returns to London, she encounters a shocking twist: her former fiancé, Hamish Ascot, has taken control of his late father's business and demands her family home in exchange for her father's cherished ship. This revelation propels Alice on a nostalgic journey, guided by the mysterious butterfly, Absolem, which leads her back through a magical mirror into the whimsical world of Wonderland.
Upon her reentry into this topsy-turvy realm, Alice is welcomed by a host of beloved characters, including the kind-hearted White Queen, the meticulous White Rabbit, the quirky Tweedles, the slumbering Dormouse, the bewildered March Hare, the relentless Bloodhound, and the crafty Cheshire Cat. They express their deep concern, as the typically cheerful Mad Hatter is acting more erratic than ever due to the disappearance of his family.
Determined to help the distressed Hatter, Alice attempts to soothe him, but her words fall flat as he clings to the belief that his loved ones are still alive, escaping the jaws of the ferocious Jabberwocky. In a bid to restore Hatter's composure, the White Queen sends Alice on a mission to seek out Time, hoping to persuade him to help rescue the Hatter's family.
However, the White Queen warns Alice of the dangers associated with altering the past, cautioning her against unweaving the fabric of Wonderland's timeline. Undeterred, Alice boldly absconds with the coveted Chronosphere, an extraordinary artifact that allows her to manipulate time itself, embarking on a treacherous journey through the twisting currents of time.
Her adventure leads her to Time's ominous Castle of Eternity, where she meets the enigmatic Time. Initially dismissive of her request to change the past, Alice seizes the moment to snatch the Chronosphere and travel back in time. She unexpectedly finds herself at the Red Queen's coronation, witnessing a younger Mad Hatter mock the Queen for her comically disproportionate headpiece.
In the wake of her father's death, the Red Queen's rage culminates in a tantrum that causes her head to inflate hilariously, highlighting her distorted psyche. As Alice navigates the complex past between the Queens, she becomes determined to reshape the Red Queen's destiny to avert the Jabberwocky's grasp on Hatter's family. Meanwhile, the young White Queen sneakily steals a tart, deftly diverting blame to her sister, resulting in a tearful exit from the castle.
Observing this unfolding drama, Alice seizes the chance to impact events by knocking aside a clock traversing the bustling square. Though her actions seem effective, they ultimately fail to save the White Queen from an unfortunate injury. Confronted by a weary Time, Alice is reprimanded for jeopardizing the delicate nature of time itself.
In a desperate effort to amend her mistakes, Alice retreats to the real world, only to find herself institutionalized, suffering from a diagnosis of female hysteria. With her mother's guidance, she escapes this confinement and returns to Wonderland, where she witnesses the Jabberwocky strike. To her astonishment, she discovers that Hatter’s family is alive but trapped by the Red Queen's merciless Red Knights.
Upon returning to the present, Alice finds the Mad Hatter on the brink of death. Her heartfelt tears breathe new life into him, restoring his true self. The inhabitants of Wonderland rally at the Red Queen's fortress, only to learn that Hatter's family was diminished and imprisoned within an ant farm. The Red Queen seizes the moment to capture them and steal Alice's Chronosphere, causing chaos and threatening to unravel time itself.
As both Queens face off in a heated dispute, a time paradox manifests, warping their forms before threatening to dissolve Wonderland itself. With everything at stake, Alice and the Hatter plunge down another tumultuous path through time to reclaim the Chronosphere. Racing against reality's unraveling threads, Alice manages to grasp the Chronosphere just as calamity strikes, rekindling harmony in the universe.
In the aftermath of this temporal turmoil, the Mad Hatter joyfully reunites with his family, a testament to love and redemption. Meanwhile, the White Queen offers a sincere apology to the reformed Red Queen for her earlier treachery, sentiments echoing an understanding forged through trials.
As Alice prepares to leave Wonderland and return to her world, she faces yet another hurdle: her mother's refusal to relinquish control of Alice's cherished ship to the wily Hamish. Undeterred, Alice teams up with her mother to navigate their future, setting forth on exhilarating adventures that lie ahead.
