On Walter's 50th birthday, he stood at a crossroads in his life, looking back at the past and looking forward to the future.His life is full of complex emotions and challenges. His academic qualifications far exceed those of the high school chemistry teacher he teaches now. He has a rebellious son and a pregnant wife, and his introverted personality often makes him feel out of tune with the world..However, today, he learned that he had lung cancer and only had two years left.

This news was like a heavy hammer, instantly crushing Walter's spirit.He felt the world around him become numb and unable to feel any emotion.He tried his best to hide this fact from his family, but he knew he had to make a choice.

Walter decided to seek advice from his brother-in-law, who worked for the Drug Enforcement Administration.However, while waiting for his brother-in-law, he witnessed a shocking scene: his former student Jesse jumped out of the window of the building and fled to his car.Walter followed immediately, he wanted to know what was going on.

That night, Walt follows Jesse, and a conversation between the two reveals a surprising plan: they intend to make drugs together.Walt was in charge of manufacturing amphetamines, while Jesse was in charge of selling them.This decision put Walter into a deep contradiction. On the one hand, he wanted to leave some wealth for his family, but on the other hand, he knew that this was illegal behavior.

The next day, Walter stole chemicals from the school, and the two hid in the RV together and started making drugs.Walt used his skillful skills to create amphetamines that Jesse was full of praise for.However, their plan didn't go as smoothly as they imagined.

Jesse brought the drugs to the drug dealer. The drug dealer knew that Jesse and Amy Luo had previous criminal records, so he wanted to take risks.He threatens Walt with Jesse and Amylo's lives to get him to hand over the amphetamine formula.Walter reluctantly agreed to the drug dealer's request.However, while demonstrating the amphetamine making process, Walter managed to add the wrong chemicals, creating a gas that successfully trapped the drug dealer and knocked him out.

Walt and Jesse took the opportunity to escape the scene in their RV, but the RV suddenly broke down.At this time, a police car suddenly appeared, and Walter nervously took out his gun and prepared to fight, but in the end it was discovered that it was just a false alarm.They were able to escape the police.

Walter knew they couldn't stay in this place any longer.He drove the RV back to town and hid the drug dealer's body in Jesse's house.He knew it was a dangerous move, but he had no choice.
