The case wasn’t just cold -- it was ice-cold. But the murder of Miriam Walker had a pretty high profile in the middle of a tough re-election campaign, so the Cook County sheriff assembled a task force to get results... and put Sergeant Frank Leal on it. Leal is still getting over the death of his partner and some wounds of his own, both emotional and physical, so working as part of a team might be tough. It doesn’t help that a lot of people don’t really want the case solved…including Miriam Walker’s husband and the men he hired to take care of Miriam for him. Leal isn’t even sure he can trust the rest of the team, but he’s got a job to do, and he’s not going to quit until he finishes it…no matter who gets in his way.
