The Bar Association disbars attorney Tyler Cradon when it appears that he was implicated in the murder of a prominent vice crusader.

Placed in Roberts' office, running a front for Cradon, Joan is taught every trick of the trade. With her cases all prepared for her, she goes from one courtroom victory to another, soon becoming the darling of the underworld and the despair of all law-enforcing authorities.
