There's no point in watching this if you're not into Acker Bilk's distinctive style of jazz. The story itself is almost irrelevant and pretty far fetched! He and his band have been in and out of prison - using their band's touring as a front for some grand larceny, but really not having the wits to get away with anything afterwards. Luckily, the prison governor (Geoffrey Sumner) is an avid fan of the music, so they continue to get a pretty easy ride whilst behind bars plotting more daft criminal antics. All the while, we are treated to a selection of his music (co-written with Norrie Paramor who, cleverly, only features the once!) and a duet or two with Carol Deene. It's harmless fun that delivers a sort of "Carry On" feel to the crime caper aspect, but it's really just a showcase for the man and his music. Enjoy it for that.
