The top mob boss in Miami, Ransom Oliver has extended the order for the execution of Penelope Lane. Killing Penelope would eliminate the last link to the failed drug and weapons smuggling operation in Bullet. Soon, Penelope vanishes from a psychiatric hospital in Bullet where she was incarcerated for the double-murder of the Drummond real estate couple.

Cutter wants to find her and save her from Oliver’s assassins. He elicits the help of former SBI partner Alex McBain to search and locate Penelope. Soon, Cutter learns about a bizarre connection between his dead wife Jenni, Penelope, and an exotic dancer stepsister of Penelope’s who will reveal shocking secrets about Penelope’s past. Meanwhile, Oliver has more devious ambitions in mind. He has set up a drug headquarters in an abandoned Miami church and is using it as a front for the smuggling in of biological contraband from the Far East.

Oliver plans a biological attack as a cover for a bank heist that could land him the biggest take in history but also result in countless casualties. To stop him, Cutter must secretly bring together a group of operatives to infiltrate Oliver’s criminal network and eliminate an organization that threatens to rain terror on the city of Miami and destroy the sanctity of the Sabbath Day.
