Sam Callahan is "moonlighting as a political tracker, paid to hide in crowds and shadow candidates, recording their missteps for use by their opponents. One night, after an anonymous text tip, Sam witnesses a congressional candidate and a mysterious blonde in a motel indiscretion that ends in murder, recording it all on his phone. Now Sam is a target. Set up to take the fall and pursued by both assassins and the FBI, he is forced to go on the run."
