Sleepers East(1934)

No good deed goes unpunished for Lena Karelson (Wynne Gibson), hooker with a heart of gold trying to go straight in the big city. Covering a bachelor party for a friend in need, Lena winds up at a gambling house where she is the sole witness when Mayor Wentworth's drunken lout of a son shoots the owner. Wentworth's political machine wants Lena to falsely incriminate mob boss Callahan to bolster their re-election campaign. Callahan's mouthpiece nabs Lena first, conveying her stealthily by train from Toledo to New York to prevent her from testifying against the big boss. A midnight special smash-up, a tense courtroom finale and true love triumphant round out this typical Fox pre-Code programmer, released just before the Legion of Decency dropped the hammer in 1934.
