A Vice detective is murdered during a drug buy.

His partner—in Vice and in life—witnesses the shooting and immediately goes code black, a law enforcement term for going blank during an extremely stressful situation.

Months later, after being medically and psychologically cleared to return to duty, she is ambushed and killed during what appears to be a routine traffic stop.

Riley Scott must try to connect the dots that lead him into the world of drug smuggling, inter-office relationships, and street justice before another officer is murdered in a similar ambush, and his own life is placed in peril.
