Four US Navy SEALS departed one clear night in early July 2005 for the mountainous Afghanistan-Pakistan border for a reconnaissance mission. Their task was to document the activity of an al Qaeda leader rumored to be very close to Bin Laden with a small army in a Taliban stronghold. Five days later, only one of those Navy SEALS made it out alive.

This is the story of the only survivor of Operation Redwing, SEAL fire team leader Marcus Luttrell, and the extraordinary firefight that led to the largest loss of life in American Navy SEAL history.
