Robbed of their take from Season One's heist, the Hill gang is left broke and stranded in the South of Spain. Trying to mount a legit recovery, they run afoul of corrupt local police and get caught up in kidnapping, blackmail and other criminal activities.

Lily and Lotti try to escape their confinement while Vic and Billy hatch a plan to break them out. Meanwhile, Charlie, Albert and Hate ‘Em take a different approach, agreeing to facilitate a dangerous arms deal in exchange for the girls' freedom.

The gang continues its efforts to free Lily and Lotti while dirty cop Carlito Blanco assigns Albert a hijack job with seasoned operative Ines. Everyone reunites at the mayor of San Toledo's house, where they learn the town's dirty dealings go deeper than they'd imagined.

As the gang rethinks its plan for surviving San Toledo, Albert sets out to get close to the mayor. Billy lands his first professional fight. Lily and Vic's marriage suffers while Albert and Ines's relationship deepens.

Vic embarks on a rogue mission while Lily finds some independence with an American ex-pat. While pulling off a job for Mayor Ortega, Albert learns some intel that might break the mayor's grip on the gang. Meanwhile, an Interpol agent comes to town on a mission.

Mayor Ortega delivers an ultimatum to Albert about Vic's behavior. Ines drops a bombshell about her identity, further complicating the gang's already precarious position. Billy's best intentions blow back on him.

Albert's actions against Vic get him back in the mayor's good graces—and back on the team pursuing Sylvia Garcia—while Interpol Agent Picket makes his move against the gang. With double crosses piling up, Lily and Charlie assume leadership roles as the diamond heist comes to a climax.

The gang reconvenes at a safe house but must face unfinished business between Albert, Ines and Mayor Ortega. At last, they rally together to face the mayor's forces in a final assault.

Albert tries to make a deal with Mayor Ortega to guarantee their safety, but a shootout shuts down negotiations. The Hill gang runs back to the Bunker Bar, pursued by the mayor for a final showdown.
