Troll

The Potter family arrives at a newly rented apartment complex in San Francisco and begins the process of unpacking. Tension and oddities surface as they settle into the unfamiliar building. The move marks the calm before the magical storm to come.

While unpacking, Wendy is confronted by a grotesque creature wielding a glowing ring. The creature abducts her, taking on Wendy's appearance and beginning the nightmare. The attack signals the start of the Troll's reign of transformations.

The troll moves from apartment to apartment, transforming each space into a lush, otherworldly realm. It begins spawning fairy-tale creatures like goblins, nymphs, and elves, reshaping the living spaces into a magical world. The tenants are drawn deeper into the surreal change.

Colossal shifts in Wendy's mood and behavior become noticeable as she grows more aggressive. The family chalks it up to stress from moving, unaware of the troll's ongoing influence. The house and its hallways echo with strange, forest-like whispers.

Harry Jr. seeks comfort and finds Eunice St. Clair, an enigmatic older woman who reveals herself to be a witch. She becomes a guide through the increasingly surreal landscape. Their bond deepens as danger closes in.

Eunice explains the ancient conflict between fairies and humans and reveals how Torok was mutated into a troll as punishment. The tale frames the world as living inside the very apartments now transformed. Knowledge of the past sets the stakes for the battle ahead.

Torok seeks to regain power by keeping Wendy alive as a coveted princess who can restore his realm. The narrative establishes the stakes for the girl caught between two worlds. Eunice and Harry Jr. realize he will stop at nothing to reshape reality.

Eunice and Harry Jr. discover that every apartment has become a gateway to the magical world. The family must navigate this new landscape to find Wendy and resist Torok's encroaching influence. The line between normal life and fairy tale blurs completely.

Eunice passes on a magic spear capable of killing the largest and most vicious creature in the realm. The weapon becomes a critical tool in the coming confrontations. It symbolizes the last sliver of hope for the family's rescue.

Torok strikes Eunice, mortally wounds her, and mutates her into a tree stump. Her fate leaves Harry Jr. and Wendy facing the looming threat alone. The loss marks a turning point in the battle for their world.

Harry Jr. locates Wendy trapped inside a glass coffin and frees her from the enchanted prison. In the ensuing clash, he loses the spear to a great batlike monster, severing their protective edge against Torok. Courage and grit drive the rescue.

In a desperate bid to protect Wendy, Torok manually kills the monster and destroys his own fairy realm to avert further catastrophe. The magical world begins to collapse around them, forcing the family to flee. The moment marks the end of the parallel world as they know it.

The Potter family escapes just as police arrive to begin investigating the wreckage. Eunice is restored to her human form and bids them farewell before departing the scene. The house returns to relative normality, though the memory of the other world lingers.

During the investigation, one police officer steps into a remaining fragment of the fairy world. Torok's arm rises, reaching for the officer with his ring as the threat lingers beyond their world. The ending leaves a chilling sense of unfinished business.
