(Robert Armstrong) which eventually subsides as time passes, but not before McCord openly mocks and derides Davis' attempts at training . However, Davis is attracted to McCord's sister Kay (Margaret Lindsay) which strengthens his determination to remain passive despite McCord's efforts to rile him. Meanwhile, MacKay retires and buys a resort lodge out in the woods of Wisconsin. His men, free of his restraint, embark on a crime spree. Hamstrung by existing laws (federal agents have to get local warrants and are not even allowed to carry guns), the head of the G-Men pleads for new laws to empower his beleaguered men. They are enacted with great speed. Davis identifies one of the perpetrators, Danny Leggett (Edward Pawley), by his superstition of always wearing a gardenia.

Jean finds out where he is hiding and telephones Davis, only to be shot by her husband. Davis bolts from his hospital bed, has some final words for the dying Jean, sneaks inside the garage and rescues Kay. Collins is shot to death by McCord as he tries to drive away.
