This is a crime story. A crime story of the usual sort. The hero is an ex-criminal who makes a success of going straight. The plot unravels satisfactorily and the wicked are justly punished. The ancient crone who owns it is waiting for her grandson, who has just been released that day from Sing-Sing. Also waiting are two of his gang, and the 18-year-old daughter of one of them, who boards with the grandmother. Expectancy runs high, as the grandson is the acknowledged leader of the gang and the girl has now decided that she's old enough to join them in their criminal enterprises. A bohemian painter who has his studio in the house is also intrigued by not only the idea, but the very low-life nature of these characters. Has now seen the error of his ways and determined to go straight! Shock and disgust ensue. The gang will now go it without him preying upon the 'swell' members of wealthy society with, incidentally, the aid of corrupt cops. This does not sit well with the grandson, who has suddenly fallen in love with the girl.
