Struggling artist Freya Bell, teetering on the brink of creative oblivion, finds herself drawn to the Ashgrove Complex, a dilapidated building in the heart of the eccentric city of Aethelburg. Its peeling paint and fractured brick whisper promises of affordable rent, a siren song Freya can't ignore. But the Ashgrove holds a secret, a chilling stipulation hidden within its labyrinthine lease: every thirteenth day, Freya must vacate her apartment for a mysterious "Special Tenant."
Desperate, Freya signs, unknowingly binding herself to the building's uncanny rhythm. With each passing thirteen-day cycle, unsettling changes manifest in her studio. Furniture rearranges itself into unnerving still lifes. Origami birds, folded from her own sketchbooks, perch precariously on shelves. The bathroom mirror flickers with glimpses of alternate lives, paths not taken, and a past she desperately tries to bury. The Ashgrove, once a refuge, transforms into a disorienting labyrinth, its hallways stretching into an Escher-esque infinity.
Her investigation into the Special Tenant's identity plunges Freya into the Ashgrove's strange world. She encounters its enigmatic residents: Eileen, a perpetually knitting woman who speaks in riddles; Jesus, the groundskeeper who warns of unseen infestations spreading through the building; and Alejandra, a rival artist whose ambition mirrors Freya's buried desires. Each interaction deepens Freya's understanding of the Ashgrove's power, blurring the lines between the tangible and the imagined.
A terrifying realization dawns: the Special Tenant is not a stranger but a reflection—one of thirteen Freyas existing in parallel realities, all tethered to the crumbling Ashgrove. The "infestations" are not insects but manifestations of Freya's anxieties, her self-doubt taking monstrous form. The antique key, appearing on her wall after the first thirteenth day, becomes a symbol, a desperate plea from another Freya urging her to unlock the dormant potential she has buried deep within.
The thirteen realities are on the verge of collapse. The Special Tenant, communicating through subtle manipulations of Freya's space, is not an intruder but a harbinger, desperately trying to convey a cryptic roadmap to avert impending catastrophe. Freya's struggle to decipher the warnings becomes a race against time. With the help of her fellow residents, she must unravel the Ashgrove's mysteries and confront the fragmented reflections of her own self.
