This is a nonsensical comedy full of musical performances. Jack (John Bellusi John Belushi) and Ewood (Dan Aykroyd Dan Aykroyd) used to be music fanatics, and performing in bands is their specialty. Jack went to prison for a robbery and abandoned his music career ever since. On the day he got out of prison, Ewood came to pick him up, and the two cheerfully went to visit Sister Mary at the orphanage where they grew up, only to be told that the orphanage owed a lot of taxes and was about to close unless someone could scrape together $5000 within 11 days. The two of them are more affectionate than the orphanage, so how can they watch the orphanage "fall"? After long-term consideration, the two brothers decided to resume their music career and beat up money for the orphanage tour. As a result, the former band regrouped, and a lively group of people began to stumble on the stage. Pooling money is still a secondary problem. They have to solve a lot of troubles accidentally encountered, such as the misunderstanding of the police and the pursuit of gangs. The motivation to save the orphanage made them invincible and charming, and at the same time found their own musical dreams.
