Bernadine is back to replace Effie Perine as Sam’s secretary. She has Sam singing the blues as he dictates his report on how a man was murdered with a buzz saw. A dame with amnesia needs Sam’s help. She has a memory of a streetcar, and a man who grabbed her, but not much else. Is she married? Does she have money? Are there any clues in her purse to help identify her?
Calling the dame Poppy, Sam hits the streets. With the dame under wraps, Sam hits the nightclubs. Clues, and connections to a murder are made.
With headlines splashing the sensation of the gruesome murder over the front page, Sam has the clues and suspects coming right to his office. The giant of a man is more helpless than the casual onlooker might suspect. To learn who wants him dead, Sam has the big man hide out at the morgue.
Taking the wheel of life to a penthouse gangster, Sam hopes to learn the secret behind it. The oriental trinket could be worth a fortune to the right buyer, but Sam still has the problem of a murder, the escaped man he left at the morgue, and the dame with amnesia who came to take him away. Poppy still sticks to her story of having no memory, but Sam may have an ace up his sleeve to get to the truth.
