The New MutantsSave

The film opens with the introduction of Danielle Moonstar (Blu Hunt), a young Native American teenager whose Cheyenne reservation community is being destroyed by an unseen supernatural force. Danielle's father attempts to rescue her during the destruction but is killed during the escape. Danielle wakes up alone in a heavily-secured rural medical facility identified as a private psychiatric hospital. The facility's only staff member appears to be Dr. Cecilia Reyes (Alice Braga), a soft-spoken physician who informs Danielle that her father is dead, that she is the sole survivor of the reservation incident, and that she has been admitted to the hospital for psychiatric evaluation pending an eventual transfer to the Xavier School for Gifted Youngsters.

The hospital's patient population is limited to a handful of mutant teenagers, each of whom has been admitted for similar mutation-related psychiatric concerns. The other patients are introduced gradually: Rahne Sinclair / Wolfsbane (Maisie Williams), a Scottish lycanthropic mutant raised in a Christian-fundamentalist community; Sam Guthrie / Cannonball (Charlie Heaton), a coal-miner from Kentucky whose superhuman propulsion abilities had emerged during a mining accident that killed his crew; Roberto da Costa / Sunspot (Henry Zaga), a Brazilian solar-powered mutant whose pyrokinetic abilities had emerged during a romantic encounter that killed his girlfriend; and Illyana Rasputin / Magik (Anya Taylor-Joy), a Russian-emigré sorceress whose dark-magic abilities and obvious dislike of authority make her the group's most-volatile member.

The hospital's daily routine consists of individual and group therapy sessions, controlled exercise activities, and the gradual building of trust between Dr. Reyes and her patients. The facility's only obvious security feature is an invisible force-field perimeter that Dr. Reyes generates personally through her own mutant power; the perimeter prevents the patients from leaving the property. The patients are told that they are being psychiatrically prepared for eventual integration into the broader X-Men community; the institutional framing is presented as therapeutic care rather than detention.

Danielle's integration into the patient community is complicated by her unawareness of her own mutant abilities. Across her first several days at the facility, the existing patients experience a series of escalating psychological-and-physical incidents: Rahne suffers nightmares involving her childhood-Catholic-church abuser; Sam relives the Kentucky mining accident; Roberto encounters his dead girlfriend in mirror-and-window reflections; Illyana confronts her childhood-sexual-abuse traumas through magical-dimensional incursions. The incidents are initially attributed to ordinary stress-induced flashbacks, but the patients gradually recognize that Danielle's arrival has coincided with the increased frequency of supernatural manifestations.

Danielle's actual mutant ability is gradually revealed through the patients' growing recognition. She is a pull-out-thoughts telepath whose unconscious projection of others' deepest fears can produce physical manifestations in the surrounding environment. Her unsuppressed fear-projection abilities are the source of every patient's experienced trauma; her own latent mutation is responsible for the destruction of her Cheyenne reservation. Danielle's discovery of her own complicity in her father's death produces a substantial emotional crisis that the other patients must coordinate to help her process.

Dr. Reyes's true affiliation is revealed during the picture's middle act. The hospital is not, as the patients have been told, a satellite facility of the Xavier School. It is operated under the auspices of the Essex Corporation, a private mutant-research organization run by the never-on-screen Nathaniel Essex / Mister Sinister, whose business model is identifying high-power mutants for eventual weaponization and corporate-sale. Dr. Reyes's role is to assess each patient's combat-utility before selecting the most-valuable for Essex Corporation's transfer protocols. The benign-therapy framing has been a deliberate manipulation.

The patients' discovery of Dr. Reyes's true role produces the picture's primary conflict. Their coordinated escape attempt from the facility is complicated by Dr. Reyes's force-field perimeter and her broader psychic-disruption abilities. The patients' multi-pronged assault on the facility's central control room produces a sustained close-quarters battle. Dr. Reyes is killed during the engagement through Illyana Rasputin's targeted use of her Soulsword weapon; the force-field perimeter collapses with her death.

Danielle's escape from her own fear-projection abilities provides the picture's third-act crisis. The Demon Bear, a giant supernatural creature manifested from Danielle's unprocessed childhood fears, emerges through her dimensional fear-projection field and begins a coordinated assault on the facility. The Bear's primary target is Danielle herself; her death would resolve the fear-projection field and end the supernatural threat. The other patients, having recognized that Danielle is both the source and the only person capable of defeating the Bear, refuse to allow her to surrender. They form a coordinated defensive perimeter around her while she works through her psychological resistance to confronting the manifestation directly.

The Demon Bear confrontation is the picture's primary action setpiece. The patients' coordinated abilities — Rahne's lycanthropic-combat aggression, Sam's propulsion-based ramming attacks, Roberto's pyrokinetic discharges, Illyana's Soulsword-and-magical-armor combat-mode — distract the Bear long enough for Danielle to access her processed-trauma psychological state and reabsorb the manifestation back into her unconscious. The Bear is reduced to a small cub-form that Danielle takes physical custody of as her permanent emotional companion. The facility's residual security infrastructure collapses; the patients are free to leave.

The film's epilogue establishes the new status quo. The five patients depart the facility together, headed toward an unspecified destination that has not been compromised by Essex Corporation surveillance. Their long-term plans are deliberately ambiguous; the picture closes on the suggestion that they will continue together as an ad-hoc team. The New Mutants grossed $49 million globally on an $80 million budget, an underperforming theatrical release that effectively closed Fox's X-Men franchise before the Marvel Studios-led continuation. The picture's troubled three-year delay between completion of principal photography and theatrical release was widely attributed to studio-acquisition disruption caused by the Disney-Fox merger; the COVID-19-affected theatrical-release window further damaged its commercial prospects.

Anya Taylor-Joy's Illyana Rasputin / Magik performance was widely cited as the picture's strongest individual element. Taylor-Joy's mid-career rising-stardom commitment to the role's mixture of dark-humor, supernatural-magic, and trauma-processing dramatic range elevated the picture beyond its broader narrative weaknesses. Maisie Williams's Rahne Sinclair / Wolfsbane role provided the film with one of its most-emotionally-grounded character throughlines; the actress's chemistry with Blu Hunt's Danielle Moonstar formed the picture's tentative romantic-relationship subplot. Director Josh Boone's previously established credits in The Fault in Our Stars (2014) had positioned him as a primarily-YA-relationship-genre filmmaker; his pivot to horror-genre material was widely cited as one of the picture's most-interesting creative choices, even as the production's troubled delays prevented the picture from receiving the audience reception it might have deserved under different release conditions. The picture's broader commercial failure ended any planned New Mutants sequel ambitions, although the franchise's underlying intellectual property remains valuable for potential future MCU adaptation. The film's horror-genre tonal direction was widely cited as one of its most-distinctive creative choices despite the broader-narrative-execution problems; the picture's commitment to depicting mutation as psychologically-traumatic body-horror rather than power-fantasy heroism was praised by critics as an unusual approach within the X-Men cinematic continuity.
