Covenant

Threats to the free world never end.
Their job is never done.

At a luxury resort on the coast of Uruguay, Jessica Petrovich and a select team of Black Flagged operatives prepare to kill Dr. Anatoly Reznikov, the elusive bioweapons scientist responsible for designing and selling a lethal virus to America’s enemies. At the same time, a Mossad assassination cell moves on a Russian mafiya boss believed to have offered Reznikov’s bioweapons to the Iranians.

There's only one problem--BOTH TARGETS ARE LOCATED IN THE SAME HOTEL SUITE, and neither team knows the other is coming!
