How do you catch a killer who leaves no trace?

In New York City, a sniper dubbed 'The Longshot Killer' is taking out impossible targets.

Nothing links the victims - except the brutal circumstances of their deaths.

Detective Michael Bennett quickly develops a profile of the killer. Great with a gun. Probably ex-military.

A profile that his new partner, Rob Trilling, fits to a terrifying degree.

With Trilling taking ever more suspicious absences from duty, Bennett must find out the truth - before the Longshot Killer strikes again.
