The pressures to pull out of Vietnam reach a crucial turning point as a Viet Cong ambush nearly eradicates an entire American battalion and a student protest in Wisconsin turns suddenly violent in this historically probing installment of the American Experience series based on Pulitzer Prize-winning journalist Davis Maraniss' book They Marched into Sunlight. With public opinion already divided over the grueling war, the historical events that unfolded in the fall of 1967 left a nation shaken, and forever changed the lives of the soldiers fighting in a far-away land, their worried parents back home, the students who saw that war was not the answer, and the police officers and administrators who struggled to gain control over a situation that was rapidly spiraling into chaos.
