While working at the CIA, Devon McHenry is asked to become a test subject for an AI computer system developed by DARPA. In a series of "games" he is challenged to lead a team of SEALs on various missions. The CIA then sends him on a mission into Africa, and he asked DARPA if he can field-test the system. When they agree the mission is on, and Devon quickly discovers that like so many things, the mission is not remotely what he was told. A simply kidnapping turns out to have strings that lead back to the White House, and not only must he find a way to survive, he knows there will be trouble waiting if he makes it back home. Move than he ever expected his best friend is a computer named Phyllis.
