The Infiltrator

One year after the clash with his former students in upstate New York, retired Marine Warrant Officer and SERE instructor Derek Harrington is the tip of the FBI's spear in their mission to eradicate the domestic terrorist group known as Autumn's Tithe. After several successful operations intelligence points to one final camp in the remote Kentucky wilderness, and Derek prepares to take down Autumn's Tithe for good. At the same time ex-FBI Special Agent Hannah Kittle, or Sarah as she is known to the group, devises a plan to meet Derek and her one-time Bureau colleagues head on. Yet her benefactor's faith in Sarah's ability to lead Autumn's Tithe is waning, and other plans are being enacted.
