Jay Fischer, a sniper for a black ops team, is assigned to secretly watch Dr. Elizabeth Ross, a possible affiliate to a known terrorist organization. She is the creator of the Waterfall Project, a failed attempt to biologically clean infested water in third-world countries. Jay becomes her reluctant hero rescuing her from a break-in at her lab. He decides to put everything on the line to protect her after his team leader insists she is working for the terrorists. He chooses to go with his instincts believing the innocent and naive professor is being used as a pawn.
In a moment of weakness, they are both captured, along with former members of her research team. An insane businessman plans to manipulate her project into the perfect biological weapon. Jay must now put his growing feelings for Dr. Ross aside by encouraging her to develop the weapon in order to give him time to plan an escape, potentially placing a weapon of mass destruction in the hands of a madman. Jay has fallen unexpectedly in love with her and will protect her at all costs, sacrificing himself to secure her freedom.
