Seven of the prisoners at Gaunstone Gaol have been encouraged to take up Trad jazz by a music-mad governor and have formed a jazz band fronted by Acker Bilk.
The Duchess of Hartlepool – a prison reform official – arranges for the band to go on tour. They are released along with their dim-witted electrician ‘Getaway’ (Arthur Mullard) – much to the Governor’s regret.
Life is tough for the boys on the outside until they land a job at a jazz club called ‘The Thieves’ Kitchen’, and soon they have a record released and make the Top 10.
But the lure of crime still calls to them, and the boys fall for a plan suggested by the club owner and begin emptying the safes of nearby stately homes while on a tour of one-night stands.
Before long, they are back where they started – much to the delight of the jazz-loving Governor.
Acker Bilk collaborated with Norrie Paramor to write nine musical numbers for the film.
