A private intelligence organization creates a device known as the Chronosphere which allows them to cross the boundaries of time and space. Aided by a young woman capable of seeing into the past, they use the information she provides to send a retrieval team through the Chronosphere in hopes of locating new recruits. While the team is out on its first mission, the facility falls under attack. The retrieval team manages to get their latest acquisitions to safety, but is captured in the process.
The new recruits become acclimated to modern day life on Earth and are provided with extensive military and intelligence training. When a key member of the organization is killed and valuable information is stolen, the recruits stop asking questions and start seeking answers. Their quest takes them from the jungles of Peru to the streets of Chicago. The deeper they dig and the more they learn about those involved, the more disturbing the puzzle becomes. As Armageddon looms, villains will rise, cities will fall, and relationships will be tested.
