Prison warden Dr. Fazetti believes to have developed an effective new concept for the rehabilitation of prisoners by offering them the chance to take a break from their sentence if only they can find a trustworthy woman who takescare of them and vouches for them. The convicts Steinbock and Hammer-Gerd succeed in doing so. However, since they are tough guys stamped by prison fights they have their issues when it comes to discipline and it is particularly hard for them to have a lady as boss. However, Steinbock falls in love with Emilia and Hammer-Gerd promotes Maren's career as a singer. Eventually they have to go back behind bars but Emilia and Maren are now waiting for them.
