From the battleground… To the playground… A retired U.S. Air Force Pararescue Specialist gives his all to protect the children.

“UNKNOWN THREAT” – Cole ‘Mac’ MacKenna is a man in transition. He spent 20 years as a pararescueman in an elite special ops group with the U.S. Air Force. After two decades of action-packed missions, he does a friend a favor. He takes a school marshal position at a prestigious drug-infested public school to find the drug source. Soon enough, his former life of loaded weapons and death-defying rescues has been replaced by arrogant parents, self-serving politicians, and questionable employees.

When a well-connected parent abuses one of Mac’s students, he springs into action like the good old days. Unfortunately for Mac, meddling with the rich can have deadly consequences.
