Detectives McGuire and Cortes take on a gruesome homicide case in Long Beach, California, and navigate the complex role of being the murder police in an area marked by homelessness, drug abuse, and gang violence. With little but their combined decades of detective experience to go off of, they investigate personal and gang-related motives in an attempt to identify and arrest their suspect. When a severed hand is found in the desert nearly 100 miles away, their years-long investigation crosses jurisdictions, and they must connect the dots before the bloodbath continues. Saint Bloodbath explores the true story of multiple heinous crimes, but perhaps more importantly, highlights the lives and experiences of the victims, their peers, and the investigators who sought to bring a murderer to justice.
