Who killed who?
About
In the bustling heart of Manhattan, Carol and Larry Lipton are a comfortably settled middle-aged couple whose routine existence is upended when they strike up a casual acquaintance with their elderly neighbors, Paul and Lillian House. When Lillian suddenly dies of a heart attack, the Liptons are initially saddened but quickly move on, until Carol begins to notice peculiar inconsistencies in Paul's behavior that suggest something far more sinister than natural causes. Despite her husband's skepticism and desire to avoid trouble, Carol becomes increasingly convinced that a cold-blooded crime has been committed right under their noses. Driven by an insatiable curiosity and the allure of an amateur investigation, the couple finds themselves entangled in a high-stakes game of cat and mouse across the city. As they delve deeper into the private life of their neighbor, the boundaries between mundane suburban concern and dangerous obsession begin to blur, forcing the Liptons to navigate a maze of deception that threatens to compromise their safety and their long-standing marriage. Set against the atmospheric backdrop of New York City, the story unfolds as a tense exploration of paranoia, suspicion, and the question of how well we truly know the people living behind the next apartment door.
