Torres is haunted by his previous transgressions as Cook takes on a tense undercover assignment.

The unit learns the truth about a secret Torres has been keeping, as Deputy Chief Charlie Reid puts a focus on Intelligence.

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.

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.

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.
