Sean Tennant and Molly Winter are living quietly and cautiously in Houston when a troubled, obsessive stranger shatters the safety they have carefully constructed for themselves. Sean is at a shopping mall when Henry Alan Keen, scorned by a woman he's been dating, pulls out a gun at the store where she works and begins shooting everyone in sight. A former soldier, Sean rushes toward Keen and ends the slaughter with two well-placed shots becoming a hero with his face plastered across the news. Sean's newfound notoriety exposes him to the wrath of two men he thought he had left safely in his past and one of them blames Sean for his brother's death. The other wants to recover a treasure that Sean and Molly stole from him. Both men are deadly and relentless enemies, and Sean and Molly will need to draw on all their strength and devotion to each other if they hope to elude them.
