"The Dark Corner"

In the bootlegging streets of Philadelphia Pennsylvania during the prohibition era four negro detectives are assigned by a special council to patrol a section of the city called, "The Dark Corner." This section of the city got its name because the area was predominantly African American. When a group of white mobsters are mysteriously found murdered in the dark corner, the city commissioner hires four Negro detectives to protect and police the area, while investigating the murders after unsuccessfully getting results by white detectives due to lack of cooperation and answers from the negro community concerning the murders. The four detectives find themselves embroiled in corruption and controversy by mob crime families, the council that hired them, and the negro community they were hired to police.
