Bob Saginowski, a quiet bartender, works at Cousin Marv's Bar, a small establishment in Brooklyn that secretly functions as a drop bar for local criminals to launder money. Cousin Marv, his boss and the former owner of the bar, operates under the control of Chechen mobsters who use the bar as part of their operations. One night, Bob discovers an abandoned pit bull puppy in a trash can and takes it home, which leads to him forming a relationship with Nadia, a woman with a troubled past who helps him care for the dog. This new connection brings both comfort and complications to Bob's life.

One evening shortly after adopting the dog, Cousin Marv's Bar is robbed by two masked gunmen who take a significant amount of the laundered money. The Chechen mobsters demand that Marv and Bob recover the stolen money, putting them under immense pressure. As they navigate tense situations and dangerous interactions with shady characters, Detective Torres keeps a vigilant eye on Bob, suspecting he knows more than he is letting on about the criminal activities. A sequence of unsettling events begins to unravel Bob's seemingly modest existence, revealing deep-seated connections to the criminal underworld and forcing him to confront his own past and loyalties.
