Its everyone's worst nightmare. Kidnapped in a foreign country. Held indefinitely in horrific conditions, at the mercy of political forces and the will of extremists. Now, on the 20th anniversary of his release, Explorer goes inside this shadow world with America's most iconic hostage - journalist Terry Anderson - who was held for nearly 7 years in Lebanon by radical Muslims. Anderson's fellow hostages, his family and the man who risked everything to free him take us inside one of the most harrowing experiences imaginable.
