“Breaking Bad” takes place over a smaller amount of time than “Better Call Saul,” which lasted two years; about the same amount of time that Walter’s doctor gave him after his diagnosis.
2008 – Walter White received his cancer diagnosis and, spurred by life-changing news, teamed up with alumnus Jesse Pinkman to cook and sell crystal meth. Eventually, the duo entered into a business relationship with Tuco Salamanca, but their relationship came to a standstill when Tuco’s paranoia nearly got them killed. Walter’s brother-in-law, DEA Agent Hank Schrader, kills Tuco in the ensuing chaos, leaving Walt and Jesse without a distributor.
2009 – Walt and Jesse continue to expand their operations, cutting out the middleman and using Jesse’s friends as distributors. Failure, however, requires the duo to recruit Saul Goodman to help grow their criminal enterprise, meeting in turn with Gus Fring.
Walt and Jesse start working for Gus on his supercar built under the industrial laundromat. The constant defiance from Walt and Jesse leads to Gus wanting to get rid of the duo, specifically Walt. To save himself, Walt turns Jesse against Gus and successfully kills Fring, using Hector Salamanca and a wheelchair bomb.
2010 After killing Gus Fring, Walter White establishes relationships and distribution networks with Lydia and the Madrigal company. Walter’s ever-expanding drug empire is put at risk when Hank discovers that Walter is Heisenberg, thanks to some real bathroom readings.
Hank and Walter engage in an intense mind battle that ends with Hank and his teammate Steve Gomez being killed by Jack Welker and his neo-Nazi gang. The gang captures Jesse and forces him to cook for them, while Walt goes into hiding after being discovered by the authorities.
Walt eventually escapes, returns to Albuquerque to rescue Jesse, get money back for his family, and kill Jack and the rest of the neo-Nazi gang. As soon as the authorities arrived, Walt succumbed to the injuries suffered while killing Jack’s gang and freeing Jesse, who eventually died.
