BIG CITY CRIME. SMALL TOWN HEROES. Fresh out of US Marshal training, Roxanne Helton is back in Washington state with her K-9 Pronto ready to get to work with the Northwest Counter Terrorism Taskforce. But first, a long overdue reunion with her husband, Sgt Liam O'Connell, who has moved from the Benson PD to work on the taskforce alongside her. Liam only wants to take his wife on the honeymoon they were supposed to have and convince her to have the wedding their friends and family want to attend. Their reunion is cut short when they spot a Syrian general they thought they'd killed years ago on a mission. The sighting sparks a journey to the past, and an investigation that sends them up and down the west coast and tests their loyalty to the taskforce—and each other. With a terror plot underway, it's up to Liam and Roxie to work with their taskforce team members and hunt down a series of threats that could destroy the country. But with their lives on the line from an old foe and a mysterious team determined to tear them apart, this case will be like nothing they've ever faced before.
