The story begins in 1923: after an accident, a newspaper reporter needs to raise $5,000 to pay for an operation, otherwise his young sister will be crippled for life. The desperate reporter is finally able to get the cash from a shady acquaintance, Riggs. Eight years later in New York, circumstances conspire to place the reporter as the number one suspect in the murder of a showgirl. With no witness or alibi, the reporter devises a plan to smoke out the real culprit. A meeting is arranged under the cover of night and to the surprise of both men, the murderer is Riggs. Out of gratitude for past generosity to his sister, the reporter agrees not to expose Riggs, however he unwittingly leads the police to him. Riggs is found guilty, and a dramatic courthouse scene ensues.
