As he finds Skyler is deadset on getting a divorce, an unwitting Walt lands squarely in the crosshairs of a pair of Mexican drug cartel hit men set on revenge.

As Skyler's affair with her boss creates chaos within her fractured marriage, a new batch of meth that puts Jesse back in business inadvertently gets Walt involved, too.

After taking out two of his boss's street dealers, Walt realises that Gus is planning to kill him and Jesse and replace him with his former assistant.

Walt and Jesse anxiously wait to see what their drug lord boss, Gus, will do next. Meanwhile, Skyler desperately searches for clues to Walt's activities, while Hank continues his slow, painful rehab.

As he and Walt resume production, Jesse looks for a way to increase his take, while the prospects for Hank's recovery place Marie at odds with their insurance company.

Ignoring Walt's objections, Jesse goes after the drug dealers who orchestrated Combo's murder; as Hank continues to refuse to leave the hospital, Skyler presses Walt to accept her money-laundering scheme.
