A young George Jung and his parents Fred and Ermine live in Weymouth, Massachusetts. When George is ten years old, Fred files for bankruptcy, but tries to make George realize that money is not important.
As an adult, George moves to Los Angeles with his friend "Tuna"; they meet Barbara, an airline stewardess, who introduces them to Derek Foreal, a marijuana dealer. With Derek's help, George and Tuna make a lot of money. Kevin Dulli, a college student back in Boston, visits them and tells them of the demand for marijuana in Boston. They start selling marijuana in Boston. They start buying marijuana directly from Mexico with the help of Santiago Sanchez, a Mexican drug lord. Two years later, George is caught in Chicago trying to import 660 pounds (300 kg) of marijuana and is sentenced to two years. After unsuccessfully trying to plead his innocence, George skips bail to take care of Barbara, who dies from cancer. Her death marks the disbanding of the group of friends; even his friend, Tuna, flees their vacation home in Mexico and is never seen again.
While hiding from the authorities, George visits his parents. George's mother calls the police, who arrest him. George is sentenced to 26 months in a federal prison in Danbury, Connecticut. His cellmate Diego Delgado has contacts in the Medellín cocaine cartel and convinces George to help him go into business. Upon his release from prison, George violates his parole conditions and heads down to Cartagena, Colombia to meet with Diego. They meet with cartel officer Cesar Rosa to negotiate the terms for smuggling 15 kilograms (33 lb) to establish "good faith". As the smuggling operation grows, Diego gets arrested, leaving George to find a way to sell 50 kg (110 lb). George reconnects with Derek in California, and the two sell all the cocaine. George then goes to Medellín, Colombia, where he meets Pablo Escobar, who agrees to go into business with them. With the help of Derek, the pair becomes Escobar's top U.S. importer. At Diego's wedding, George meets Cesar's fiancée Mirtha and later marries her. However, Diego resents George for keeping Derek's identity secret and pressures George to reveal his connection. George eventually discovers that Diego has betrayed him by cutting him out of the connection with Derek. Inspired by the birth of his daughter and a drug-related heart attack, George severs his relationship with the cartel.
All goes well with George's newfound civilian life for five years, until Mirtha organizes a 38th birthday party for him. Many of his former drug associates attend, including Derek, who reveals that Diego eventually cut him out as well. The FBI and DEA raid the party and arrest George. George becomes a fugitive, and his bank account—heretofore under Manuel Noriega's protection in Panama—is seized by Noriega. One night, he and Mirtha get into a fight while driving. They are pulled over by police and Mirtha tells them Jung is a fugitive and has stashed a kilogram of cocaine in his trunk. He is sent to jail for three years, Mirtha divorces him, and takes custody of their nine-year-old daughter, Kristina "Sunshine" Jung.
Upon his release, George struggles to maintain his relationship with his daughter. George promises Kristina a vacation in California and seeks one last deal to garner enough money for the trip. George completes a deal with former accomplices but learns too late that the deal had been set up by the FBI and DEA, with Dulli and Derek having leaked the nature and location of the action in exchange for pardons for their involvement in his prior action. George is sentenced to 60 years at Otisville Correctional Facility in upstate New York. He explains in the end that neither the sentence nor the betrayal bothered him, but that he can never forgive himself for having to break a promise to his daughter.
While in prison, George requests a furlough to see his dying father, Fred. His mother denies the request. George records a final message to his father, recounting his memories of working with his father, his run-ins with the law, and finally, too late, his understanding of what Fred meant when he said that money is not "real". An old man in prison, George imagines that his daughter finally comes to visit him. She slowly fades away as a guard calls for George. The film concludes with notes indicating that Jung's sentence will not expire until 2015, and that his daughter has yet to visit him.Johnny Depp as George Jung

Blow was a minor box office success. With a budget of roughly $53 million, it managed to rake in just under $53 million domestically, but raised just over $30 million internationally for a worldwide total of $83,282,296. Reviews for Blow were decidedly mixed. The film holds an approval rating of 55% at Rotten Tomatoes based on 136 reviews with a weighted average score of 5.8/10. The site's consensus is: "With elements that seem borrowed from movies like Goodfellas and Boogie Nights, Blow is pretty much been-there-done-that despite another excellent performance from Johnny Depp. It also becomes too sentimental at the end." On Metacritic, the film has a normalized score of 52 out of 100, based on 34 critics, indicating "mixed or average reviews". Penélope Cruz was nominated for the Golden Raspberry Award for Worst Actress for her performances in Blow as well as Captain Corelli's Mandolin and Vanilla Sky.
Rob Gonsalves from eFilmCritic.com gave the film 4 out of 5 stars stating: "Blow isn't really a classic, but it's a sobering story well-told." Roger Ebert gave the film 2½ out of 4 stars, but questioned the value about making Jung the subject of this film, stating: "That's the thing about George [Jung]. He thinks it's all about him. His life, his story, his success, his fortune, his lost fortune, his good luck, his bad luck. Actually, all he did was operate a toll gate between suppliers and addicts. You wonder, but you never find out, if the reality of those destroyed lives ever occurred to him." David Nusair of Reel Films also questioned making a film about Jung, stating "The biggest problem with Blow is that Jung is such a complete moron." Nusair concludes that while it "is not a bad film ... the central character of George Jung just doesn't seem worthy to be the center of attention." Christopher Smith from Bangor Daily News gave the film a "D+", stating "Blow is ultimately more about charisma than it is about truth, more about Depp's smooth strut and tousled hair than it is about George Jung's fatal flaws—his stupidity, desperation, ego and small-town greed."
