In Broward County, FL, a Mexican immigrant collapses outside of his home. EMS responds and finds the man suffering from severe injuries to his face and head. He is rushed to the hospital where he dies the next afternoon.
Lead Detective Kevin Forsberg investigates and discovers that the man had been beaten and robbed a week earlier. He says, "Had he gone to the hospital sooner more than likely he would have survived."
Forsberg's partner, Detective Valerian Perez, accompanies him to meet with the victim's neighbors.
Forsberg calls in a B.O.L.O. (Be on the Lookout) for a Jeep that was stolen during the robbery.
Back at the office, Forsberg and Perez look up a potential suspect in their computer database.
On a sunny day in the St. Clair neighborhood of Cleveland, OH, shots ring out at a local car wash.

Lead Detective Art Echols was born and raised in Cleveland. He went to school in the St. Clair neighborhood but he observes that, "time has changed that area."
Det. Echols' partner Detective Lem Griffin is a 23-year veteran of Cleveland PD.
Echols and Griffin are briefed about their victim at the crime scene.
Detectve Echols walks through the crime scene and tries to reconstruct what might have happened.
A Cleveland Crime Scene Tech photographs evidence on the scene.
They determine that the victim was shot nine times from two different guns. Multiple shell casings are collected from the crime scene.
Echols and Griffin need to find a witness to the murder, but no one wants to talk.
Det. Echols learns that his homicide may be a revenge killing for a case that happened two months earlier. "Allegedly [our suspect] made the statement before he ran away, 'I did what the police didn't do." Echols now has a possible motive, but he still needs an eyewitness to identify his suspect.
Twenty-four hours later a possible witness comes in for an interview. Det. Griffin has Detective Joselito Sandoval act as a blind administrator (someone without any knowledge of the case) for a photo lineup.
In Broward County, Detective Perez looks for their suspect in surveillance footage from a bar where his victim was drinking the night of the robbery.

Three days later, Detective Perez gets a call from the suspect's attorney. They want to meet to discuss what happened. The meeting ends with the suspect accusing another man of beating up the victim.
Cleveland's Det. Art Echols is back to having no leads after his possible witness is too afraid to ID the suspect. "We need a witness to stand up and say 'he did it.'" As the clock winds down, Echol's suspect still walks the streets.
Finally, Det. Griffin gets a call about a man who claims he witnessed the murder and wants to talk.
Griffin and Echols celebrate the good news with a fist bump and a bro hug.
Patrol heads out to look for Echols' suspect.
A few days later, Echols is able to close his case. "There's no winners in the case; everybody loses."
