In June 2005 four US Navy SEALs left their base in Afghanistan for the Pakistani border.

Their mission was to capture or kill a notorious al-Qaeda leader known to be ensconced in a Taliban stronghold surrounded by a small but heavily armed force. Less than twenty-four hours later, only one of those Navy SEALs was alive.

This is the story of team leader Marcus Luttrell, the sole survivor of Operation Redwing. Blasted unconscious by a rocket grenade, blown over a cliff, but still armed and still breathing, Luttrell endured four desperate days fighting the al-Qaeda assassins sent to kill him, before finding unlikely sanctuary with a Pashtun tribe who risked everything to protect him from the circling Taliban killers.
