In the heart of Manhattan, a freshly renovated brownstone becomes the backdrop for a quiet, exacting life. Bart Hughes is a senior investment banker whose days are measured by spreadsheets, deadlines, and the perfect order of his home. The city outside buzzes with ambition, but within his walls, every detail is curated to reflect control and stability—a sanctuary built on routine and the promise of professional ascent.

When a surprisingly large rat makes its home in the very place Bart has painstakingly refined, the fragile equilibrium shatters. The unwelcome guest arrives just as Bart grapples with a career crossroads: a pivotal project is reassigned, and his superiors demand an ambitious reorganization plan under a crushing two‑week deadline. At the same time, his family life teeters on the edge—his wife Meg and son Peter are largely out of sight, while his demanding boss Eliot Riverton and observant secretary Lorrie Wells sense an undercurrent of strain. The intrusion of the rodent forces Bart to confront not only the physical mess it creates but also the deeper anxieties that linger beneath his polished exterior.

The film balances the sleek, cold precision of high‑finance Manhattan with the gritty, chaotic world of urban wildlife. Its tone is a tense blend of dark humor and psychological unease, where the ordinary becomes unsettlingly surreal. Each creak in the floorboards and each droplet of water from a leaky faucet feels amplified, echoing Bart’s internal battle between order and disorder.

As the rat’s presence persists, it becomes a stark metaphor for the forces that threaten to unravel Bart’s carefully constructed life. The story hints at a looming showdown—not just with a creature, but with the raw instincts and hidden fears that lie dormant in the heart of the city and within Bart himself.
