In a small suburban town, four high school friends discover their shared obsession for old-school horror films screening at a local theater every afternoon at 4:30 pm. The group—consisting of Emma, a curious and imaginative teen; Tony, her sarcastic best friend; Lisa, the quirky film buff; and Dave, a timid artist—find themselves drawn into the unique, nostalgic escape each showing provides. As they delve deeper into these cinematic worlds, they notice strange parallels between the movies and their everyday lives. Each film uncannily reflects unresolved issues they secretly contend with—from fractured relationships to personal insecurities—compelling them to confront problems they would rather ignore.

Intrigued by these uncanny coincidences, the friends embark on a quest to unravel the mystery behind the films and their remarkable connection to reality. Guided by clues found in cryptic posters lining the theatre walls and dialogue within the films themselves, they explore hidden aspects of their town and own lives, forming a tighter bond as they unravel curiously aligned story arcs. Midway through their journey, the friends unveil a mysterious dark secret intertwined with the theater's past that challenges their perceptions of fate and fiction. Their investigation gradually blurs the lines between cinematic fantasy and tangible truth, driving them toward choices that will forever alter their friendships and personal narratives. As the tension builds, each character must find the courage to rewrite their own stories, while acknowledging the power of imagination and connection.
