Following the murder of his half-brother, legendary Army Ranger Luke Foster returns to the United States from fighting terrorists. His brother's history with a prominent New York Mafia family was no secret, so it's no surprise his life was cut short. But the Mafia enforcers don't know about Foster, his reputation as The Reaper, or that he's coming for them.

FBI Special Agent Calico Hayes is determined to stop Luke Foster from leaving a trail of bodies across the U.S. in his unsanctioned quest for vengeance. But stopping Foster's revenge proves more difficult than she expected, and sparks fly in more ways than one when the two cross paths.

While investigating his brother's murder, they uncover a sinister plan to assassinate a populous Presidential Candidate. Hayes and Foster must put purpose before passion in order to stop the diabolical plot that could trigger a World War.
