New York City detective Michael Bennett faces his most terrifying killer ever. It could be anyone. They could be anywhere.

A sniper dubbed "The Long Shot Killer" is taking out impossible targets in New York City.

As the unknown shooter's hit list mounts, Detective Michael Bennett calls for reinforcements.

Officer Rob Trilling doesn't like to talk about himself. But he has an impressive resume as a former Army Ranger who's won a Bronze Star and recognition as a sniper with NYPD's Emergency Services Unit.

​Bennett struggles to connect with the soldier, barely older than his own ten kids, especially when Trilling begins to log unexplained absences from duty.

Trilling may be more comfortable with rifles than he is with people, but only Bennett can prove whether his partner is a lonely hunter or a hardened assassin.
