In this film from late in his career, Kramer returns to Hanoi after nearly 25 years to re-envision the city’s struggle through an uncertain and daunting past, present, and future. The Vietnamese characters in the film are diverse: Kramer’s former guide from an earlier visit in 1969; a tight-rope walker in the national circus; a man who took photos of B-52s and another who lost his fingers shooting them down.
