Alex Russo and the Russo family, joined by Harper Finkle Harper Finkle and Alex’s boyfriend Mason Greybeck, prepare for another round of celebrations as Justin takes over WizTech. A student named Dominic visits the house to break the news that Justin is too busy to celebrate in person, and his flirty manner with Alex injects a spark of jealousy into Mason. To cap the moment, Jerry Russo announces a family reunion in Tuscany, Italy, and to make the voyage easier, Alex secretly creates a portal linking their Italian villa with their loft in New York. The move ruffles Jerry’s feathers, who scolds her for acting immaturely, though he can’t help but grin at her grand plan to bridge two worlds. The mood stays buoyant as the family prepares for travel, even as the promise of a long-awaited gathering looms on the horizon.
After a private talk with Dominic, Alex Russo tries to prove she’s grown up by attempting to purge the darker parts of her personality with a spell meant to expel negativity. Instead, she accidentally conjures an evil reflection of herself. The doppelgänger, Evil Alex, slips free and heads for Italy, leaving the real Alex with a growing fear that her own powers might one day betray her. Meanwhile, Max Russo catches the eye of an Italian girl while the family’s journey begins to take shape, and he’s soon swept up in a playful intrigue he doesn’t yet understand. Jerry Russo and Theresa Russo tail him with a protective urgency, hoping to keep the reunion on course as they unexpectedly cross paths with their relatives, sparking the reunion’s energy much earlier than anyone anticipated. The town’s winding streets and sunlit squares become a backdrop for a growing, if chaotic, family bond.
Evil Alex, with the aid of an unnamed wizard who is later revealed to be Dominic, uses her power to shrink and imprison [Max Russo], [Jerry Russo], and [Theresa Russo] in tiny beads. The rescue mission escalates quickly as Harper and Alex chase the captors to the Leaning Tower of Pisa, where Harper herself is captured. Dominic’s plan is chilling in its simplicity: install a spell replicator at the tower’s summit to convert mortals into beads, so he can seize control of the world by weaponizing Alex’s magic. When Alex refuses to cooperate with this catastrophe, Evil Alex intensifies her pursuit of Mason, adding a personal threat to the mounting danger.
To save her family, Alex agrees to follow Dominic’s machinations, activating the machine at the top of the tower. But just as she seems ready to turn the tide and reverse the spell, she is whisked away and branded as someone who would destroy the mortal world, a verdict that rests on Dominic’s twisted testimony. Mason doesn’t abandon her; he manages to blast open a path to freedom and frees her from confinement. The duo races back toward the tower, where a dramatic clash unfolds: good Alex versus Evil Alex in a duel that blends magic with physical combat, while Mason fights Dominic in a separate, brutal struggle. In the heat of the battle, Alex retrieves the crucial bracelet from Evil Alex’s grasp, turning the tide once more.
As the dust settles, Dominic strikes a decisive blow against Mason, and the forces of evil briefly seem to gain the upper hand. Yet the steadfast courage of the family prevails: Mason forces Dominic toward a fatal plunge from the tower, and Alex, choosing a higher path, relinquishes her powers to banish her evil self and destroy the machine once and for all. The mortals are freed, the true Alex regains her magic only after accepting that she does not truly need it to be whole, and the Russo clan—together with Harper and Mason—rejoice in a restored sense of togetherness at the reunion before they head back to the Sub Station.
In the end, the decision to linger in Italy remains strong, as Alex shares with Harper a hope that they should stay a while longer to mend the living room and savor the family’s hard-won harmony, a sentiment born from the battle’s chaos and the warmth of a found, lasting bond. The vacation-like energy of the trip gives way to a calm resolve: the family is ready to stay, not just visit, as they close the chapter on this extraordinary Tuscan chapter.
