High school chemistry teacher Walter White learns he has terminal lung cancer. In order to secure his family’s financial future, he teams up with Jesse Pinkman, a former student, to make meth in an RV.
When their first distributor, Krazy-8, tries to double-cross them, Walt kills his right-hand man Emilio with a chemical explosion and later strangles Krazy-8 himself in Jesse’s basement.
Jesse flees to his parents’ house to seek refuge from the recent horrors, but is kicked out when his parents discover a joint — which in fact belongs to his younger brother.
Walt starts chemotherapy and tells his pregnant wife, Skyler, that he agreed to let Elliott, his wealthy former colleague, help with payments. In fact, he is paying with meth profits.
