Based on journalist Martha Raddatz's same-named best-seller, `The Long Road Home' dramatizes the heroism on the front lines of the Iraq War. On April 4, 2004 - a day that came to be known in military annals as `Black Sunday' - the 1st Cavalry Division from Fort Hood was brutally ambushed, an incident that changed the U.S. military's view of Iraq from a peacekeeping mission to a fight against domestic insurgents. Across eight episodes, the series cuts between the battle in Iraq and the homefront in Texas, where wives and families anxiously await news for 48 agonizing hours.
