Untamed Youth (1957)
Mamie Van Doren and Lori Nelson star as hitchhiking chanteuses, Penny and Janey Lowe, who are arrested and brought before Judge Steele (Lurene Tuttle).
They are unfairly tried and sentenced to a Californian prison farm owned by the evil Russ Tropp (John Russell), who is secretly married to the corrupt judge.
However, their scantily clad exploitation is exposed by Tropp/Steele's hunk son, Bob (Don Burnett), although not before Van Doren has belted out a quartet of woeful ditties that leave room for only one tune from rocker Eddie Cochran.
A crisis is reached when an inmate suffers a miscarriage and dies. The expected prisoner revolt takes place and the Steeles, minus Bob (who proves to be a decent sort) are brought to justice.
Penny is given the chance to appear on national TV and Janey and Bob get together.
Future Hollywood power producer Howard W Koch clearly thought he was directing a raunchy piece of rock 'n' roll rebellion here, but this prison musical is so frequently unintentionally hilarious that it eventually becomes entertaining by default.
