Apartment 1303

Janet leaves her home after a family dispute and relocates to downtown Detroit, taking up residence in the thirteenth-floor apartment 1303. A neighbor, Emily, tells her the previous occupant killed herself, planting an ominous first impression. The move marks the start of a string of unsettling events in the new dwelling.

The 9-year-old neighbor explains the fate of the last occupant, hinting at a restless history in 1303. Shortly after, Janet begins noticing strange occurrences and a creeping sense of dread. The warning sets a supernatural undercurrent for what follows.

Janet arrives with bruises she won't explain, and she resists coworkers' concerns about potential abuse. She blames the marks on sleepwalking rather than any human action. The incident foreshadows the apartment's harmful influence on her.

Feeling isolated, Janet asks her sister Lara to come home, but Lara warns against it due to Maddie's drinking and instability. They discuss options, including a hotel, which they cannot afford, and Janet also reaches out to Mark, who agrees to check on her. The plan to keep safe quickly spirals toward danger.

That night, Janet is awakened by supernatural disturbances. Mark has left to check on her, and an invisible ghost possesses Janet, triggering a deep depression and ultimately driving her toward suicide. The apartment's hauntings escalate into a deadly event.

Lara arrives to collect Janet's belongings, only to encounter the same terrifying phenomena that plagued her sister. The haunting appears personal, as if the apartment is targeting the next victim even after Janet's death. Lara's return to the apartment marks the ongoing nightmare.

A detective who has been investigating a string of mysterious tenant suicides questions Lara and begins to suspect Janet's death might have been murder. He ties the present events to a larger pattern affecting other residents, hinting at a malevolent force tied to 1303.

The detective recounts Jennifer Logan's tragic past: at 12, she moved into 1303 with her mother Mary, who later lost her job, became abusive to Jennifer, and even turned to prostitution to pay the rent. Jennifer murdered Mary and hid the body in a built-in closet, then killed herself after neighbors raised alarms and the authorities investigated. This history surfaces as a key piece in the haunting of 1303.

The detective explains that Jennifer's tragedy is part of a longer pattern of suicides and violent events linked to the apartment. Janet's case is framed as a contemporary echo of those past horrors, with the building's tenants repeatedly drawn into the same doom. The history intensifies the sense that 1303 is cursed.

Despite Janet's cryptic warnings, Lara and Maddie move into apartment 1303, hoping to stay together and confront the haunting. Soon Jennifer materializes, killing Mark by throwing him from a window. The home becomes a battleground between the living and the vengeful spirit.

Lara encounters Emily and the landlord O'Neill, who reveals the truth about his daughter and the fate of those who have claimed victims in 1303. He explains that Emily's fate is tied to the restless presence and that the family had long attempted to warn others. The explanation deepens the mystery and the sense of fatal history.

As Lara defends herself with a knife, Maddie is killed and the confrontation seems to reach its peak. The police arrive just as Jennifer slips away, leaving Lara facing arrest for Maddie and Mark's murders. The sun rises on a hauntingly quiet building, with Jennifer still seen as a warning to future inhabitants.
