Twin brothers Moke (Josh Brolin) and Jady (Peter Dinklage) rob a warehouse, but only Jady gets caught and spends time in prison. While inside, he meets and strikes deals with connected Correctional Officer Farful (Brendan Fraser), whose crooked court-judge father (M. Emmet Walsh) gets Jady sprung from prison. Moke is working at a fast-food restaurant, but is fired because he didn't disclose his criminal past. His wife (Taylour Paige) is pregnant. Farful beats Jady up at his place, and threatens him into looking for some emeralds, but he doesn't find them. The brothers decide to go on a road trip for the emeralds. They visit Bethesda (an uncredited Marisa Tomei), a lady Jady met online. They meet her pet Orangutan there smoking a cigarette. They visit awhile but leave when the Orangutan sexually harasses Moke. They then stop at a motel, where they find their mom (Glenn Close). She talks about the heist many years ago when her partner swallowed some emeralds before dying in a car crash; she buried him and left the country. She now claims to be dying of brain cancer, with less than a year to live. They agree to one last heist to acquire the buried emeralds, now worth $4 million. Meanwhile, Farful gets to Bethesda's place and she tells him about the brothers before he gets chased away by the horny Orangutan. Mom and her sons get an excavator and go to the plot, which is now a private golf club, to dig up the body of her deceased crime partner who died with emeralds in his stomach. They get the emeralds but are spotted by golf players. There is an excavator/golf cart high-speed chase, but they manage to get away. They bury the body again in a different location, and Moke discovers that Jady impersonated "Labor and Employment Bureau" to get him fired from his job. The brothers fight, but Farful arrives with a gun and demands the emeralds. The mom runs away with the emeralds and they all chase her, but she gets into a car and drives away. Farful drives a car with the brothers in the back seat, but the handcuffed brothers get into another fight and a random kick knocks Farful unconscious. The mom sells the emeralds for cash, but the twins are able to locate her and demand their share of the loot. She runs to an abandoned mall with her kids in pursuit. Farful tracks his car by GPS, appears there with a gun and is able to secure the bag of cash. But when he opens the bag, he is sprayed in the face by pepper spray. As he fires more shots in agony, he hits a propane tank which explodes, the mall giant Christmas tree falls on him and he dies. Hearing the gunshots, the mall is surrounded with cops. The mom takes the gun, tells her sons to flee, and confesses that she's not actually dying. At Judge Farful's house, Moke gives the judge his share of cash in return for his brother's gun with incriminating fingerprints. Moke arrives late for Thanksgiving dinner with his wife and her family, and is joined by Jady, who says he has seen a lawyer and created a trust under Moke's daughter's name for $2 million. A year later, the brothers share a prison Thanksgiving meal with their mom in jail, where she gets to see her new granddaughter. The brothers go outside, and Jady opens his hand to reveal two emeralds, as it shows mom had secretly swallowed them just before being arrested. In the final narration, Jady reveals there was actually three emeralds, and he kept the extra one.
