Breaking Bad (season 1) (2008)

Walter White leads a mundane life as a high school chemistry teacher, living with his pregnant wife, Skyler and his son, Walter Jr. , who has cerebral palsy. His life is complicated when he is diagnosed with stage-three terminal lung cancer. Walter decides to enter the illegal drug trade to develop a sufficient inheritance for his family before he succumbs to his cancer. He uses his chemistry knowledge to cook remarkably potent methamphetamine with one of his former students, Jesse Pinkman .

The two attempt to sell their product to a drug distributor, "Krazy-8," who believes that Walter is an undercover cop and attempts to kill him. Walter and Jesse manage to defend themselves, by kidnapping and killing Krazy-8 and his accomplice. Walter, deeply disturbed by the ordeal, breaks his ties with Jesse. Upon returning home, Walter and his family discuss long-term plans towards dealing with cancer. While Walter originally wishes to slowly succumb to his cancer rather than suffering the side-effects of chemotherapy, his family eventually convince him to undergo treatment.

Walter is offered financial assistance from his brother-in-law, Hank , who is a DEA agent, and from his wealthy friend Gretchen, but turns down both offers. Instead, Walter decides to return to producing crystal meth, and tells his family that the money he earns was actually from Gretchen. Walter then convinces Jesse that they should start selling their product to Tuco , a powerful but psychopathic drug distributor. The two begin to expand their operations by stealing a large drum of methylamine, thereby allowing them to produce large quantities of meth for Tuco. Walter begins to come to terms with his secret lifestyle, and creates the pseudonym "Heisenberg" to conceal his identity.
