As Albert, Charlie and Billy process their windfall, footage of the heist goes viral, reaching the eyes of Bob Fink, a dirty cop with old ties to the Hill family. Meanwhile, in a new scheme set up by Vic, the trio goes in on a diamond job for Saul Gold, a "businessman" who doesn't forgive mistakes.
To retrieve the stolen diamonds, Albert formulates a plan and seeks the help of his father's old accomplice. Lily finds the gold biscuit that Charlie dropped in the bathroom.
Desperate to pay back Saul before time runs out, Albert, Charlie and their new ally, Chloe Koen, fly to New York to fence the gold. But a careless mistake leaves them racing all over the city to salvage the deal. Meanwhile, Billy and Lotti plot to free the safecracker Norman from Sonny's lair.
After patching things up with Saul, the boys get a lead on liquidating the gold bars, thanks to Chloe. But the buyer, a wealthy sheik, proves finicky. The gang must think on their feet, while at the same time eluding Fink, who is moving ever closer to their treasure.
As the gang cools their heels at a country manor, a budding love triangle brings tensions to a boil. But the pressure to sell the gold tub forces the friends to work together. Meanwhile, Vic plots a prison escape with pal Hate 'Em, only to find a chilly homecoming awaiting him on the outside.
Lotti and Billy have the gold re-smelted while Chloe lines up a buyer. An on-the-lam Vic tries to sniff out his treasure while Albert and Lily try to keep him from getting recaptured. Drunken Charlie falls into the hands of Bob Fink, who is determined to extract the location of the gold.
Vic and Hate 'Em use brutish tactics to track down the location of the gold. Fink torments Charlie for information, but discovers the hard way he's not the only one with gold lust. As opposing forces converge on the gypsy camp, a misunderstanding escalates into a gunfight.
As the Hill family and gang regroup, Charlie returns with news of Jones and Dwyer's plans to sell the gold. Lily wants nothing to do with it, but Albert hits on a better idea: forget the gold and grab the cash. But first, the gang will have to do some recon inside Jones's heavily guarded lodge.
With Vic in the back of Jone's van with the gold and with Albert and Hat'em and tailing the van, it all leads down to an enthralling and action filled season finale.
