"They'll never get caught. They're on a mission from God."
The Blues Brothers - Ending Explained
⚠️ Spoiler Analysis
The Climax: After a legendary chase involving hundreds of police cars, SWAT teams, and the National Guard, the brothers reach the Cook County Assessor's Office. They barricade the door just long enough to pay the $5,000 tax bill in cash, which the clerk (Steven Spielberg) stamps, officially saving the orphanage.
The Twist/Ending: Their victory is immediately followed by their arrest. They are handcuffed and led away by a massive army of law enforcement. The film ends with the entire band in prison, performing 'Jailhouse Rock' for a captive audience of inmates, showing that while they lost their freedom, they kept their spirit and their music alive.
Alternative Interpretations
The Divine Protection / Angel Theory: A popular fan theory suggests that Jake and Elwood effectively died early in the film (perhaps during the initial bridge jump or the police station siege) or are literal angels. This explains their Looney Tunes-esque invincibility—they survive explosions, falling from skyscrapers, and rocket attacks without a scratch. The 'mission from God' is literal; they are supernatural agents who cannot die until the task is finished. Once the tax is paid, their 'magic' car instantly falls apart, signifying their divine protection has lifted.
The Golem Theory: Some interpret the Bluesmobile as a golem or magical construct, imbued with life solely for the mission. It performs impossible physical feats but disintegrates the moment its purpose is served.
