Milwaukee Police Detective Declan Tomczyk, a former Marine Corps officer, is dispatched to investigate the damaging and desecration of headstones at a local cemetery.
Initially chalked up as the handiwork of Halloween pranksters, it becomes anything but when his good friend and former squad partner is critically injured. Tomczyk is determined to track down the domestic terrorists, leading him further into danger.
This marks the beginning of a series of violent crimes, eerily similar to the "reign of terror" that paralyzed Milwaukee decades earlier. As Tomczyk probes into the mysterious leads, he teams up with FBI Agent Anne Dvorak, and a romance blossoms. With the unlikely assistance of a high school athlete and World War II veteran, the investigators scramble to identify and apprehend the perpetrators. As they close in, it becomes a race against the clock to pinpoint the next target before it's too late.
