Briscoe and Curtis have to break the mutual alibi of two girlfriends as they try to find the killer of a young black man, whose angry parents pressure McCoy to indict a young woman who claims the victim had raped her.

Curtis, angered by the attitude of an old colleague of Briscoe's, looks beyond the findings of an IAB investigation and turns up evidence of police corruption that puts the DA's office into competition with an ambitious judge and Briscoe under investigation for stealing evidence from a police lockup.
