With Gus Fring dead, Walt's transformation from well-meaning family man to ruthless drug kingpin is nearly complete. Forming a partnership with Jesse and Mike, Walt proceeds to make a killing in the meth business until the fruits of his murderous schemes are threatened by a new development in the investigation led by his relentless brother-in-law Hank.

As his young accomplice, Jesse, turns increasingly distant and hostile, Walt must deal with his estranged wife, his relentless DEA agent brother-in-law, and the ruthless kingpin manipulating the entire operation.

Abandoned by his wife, feuding with his reckless partner and hunted by a Mexican cartel, teacher-turned-meth-cook Walt faces an impossible choice: make a fortune working for a dangerous kingpin or walk away and risk everything he cares about.

As their partnership reaches new heights, Walt and Jesse begin to see the extremes of the drug trafficking business. Their trademark blue meth is making them rich, but it's getting more difficult than ever for Walt to conceal the truth from his wife Skyler, his son Walter Jr., and his DEA agent brother-in-law Hank. Walt struggles to maintain control of his life as he contends with vicious drug dealers, an increasingly distant wife and son, the impending birth of his daughter, and a strung-out business partner – all while battling terminal lung cancer.

Emmy award winner Bryan Cranston stars as Walt White is a down-on-his-luck chemistry teacher struggling to make ends meet for his wife (Anna Gunn) and physically challenged son (RJ Mitte). Everything changes when Walt receives a startling diagnosis: terminal lung cancer. With only a few years to live and nothing to lose, Walt uses his training as a chemist to cook and sell crystal meth with one of his former students (Aaron Paul). As his status grows, so do his lies, but Walt will stop at nothing to make sure his family is taken care of after he's gone, even if it means putting all their lives on the line. Executive produced by Vince Gilligan and Mark Johnson.
