The Mask 3 (2026) follows Stanley Ipkiss years after he last encountered the mischievous green mask linked to the Norse god Loki. Now living a quiet life as a comic-book illustrator, Stanley has tried to bury the past, locking the mask away and convincing himself that the chaos it created belonged to another lifetime. However, his fragile peace is threatened when strange magical disruptions begin appearing across Edge City — swirling green storms, illusions materializing in daylight, and people reporting visions of a grinning trickster figure.

Stanley soon learns that Loki’s essence has weakened, causing the mask’s magic to leak into the world in unpredictable ways. Trying to avoid being pulled back into the madness, he refuses to put the mask on again. But when a mysterious new figure arrives in Edge City — a charming yet unstable archaeologist named Dr. Mara Voss — the situation becomes impossible to ignore. Mara reveals that she’s been hunting artifacts related to Norse mythology and believes the mask is the key to restoring balance between worlds. Her fascination, however, borders on obsession, and Stanley senses that her motives are far from pure.

Trouble escalates when a corrupt tech mogul, Adrian Crowell, steals the mask after tracking its magical signature. Crowell is determined to harness its power to build a mind-control device capable of turning the city into his personal playground. Once he puts the mask on, he transforms into a distorted caricature of himself — theatrical, ruthless, and unstoppable. His reign of chaotic mischief plunges Edge City into a surreal nightmare filled with living billboards, dancing skyscrapers, and reality bending in cartoonish ways.

Desperate to undo the damage, Stanley reluctantly teams up with Mara, though he cannot shake the feeling that she, too, wants the mask for her own desires. Their uneasy alliance forces Stanley to confront the truth: the mask has always been a part of him, and denying it has only made its influence more volatile. To stop Crowell, he must once again embrace the unpredictable power he has spent years running from.

The final showdown unfolds in a twisted version of Edge City reshaped by the mask’s magic. Stanley, donning the mask once more, matches Crowell in a battle of imagination — a frantic duel of illusions, comedic tricks, and wild transformations. In the end, Stanley outsmarts Crowell by exploiting his ego, causing the mask’s magic to overload and separate from him.

After the mask is recovered, Stanley chooses not to destroy it but instead gives it to Mara, who vows to seal it away in a realm where it can no longer harm the human world. Yet as the film closes, she gives a sly smile, hinting that the mask’s story — and Loki’s mischief — may not truly be over.
