No one knows what CIA desk jockey Zac is capable of - including himself - until a routine surveillance job becomes a do-or-die mission. When a commercial flight violates restricted airspace to make an emergency landing in Iran, the passengers are just happy to be alive and ready to transfer to a new plane. All except one - who isn't who he says he is. When the agent's cover is blown, Zac volunteers to take his place, despite no training. Embarking on a harrowing journey through the mountains of Iran to the Persian Gulf and across Europe, Zac can only rely on himself to make it out alive.
