Not so much a movie as an excuse for music. Interesting mostly if you want to see the musicians (especially in the "Louisiana Gator Boys" set where one can spend most of the song going "Hey! Isn't that...".)

The basic idea is that Elwood Blues is just out of prison, Jake Blues (like, of course, John Belushi) has died, and Sister Mary Stigmata asks Elwood to mentor a young boy and to help raise money for a children's hospital. Elwood decides to put the Blues Brothers Show Band back together despite everyone's reluctance, considering what happened the last time the band performed in The Blues Brothers. Car crashes and music ensue.
