The Vietnam War devastated not only a country, but also the lives of millions, both Vietnamese, and the US soldiers who were sent to fight a war far from home. For Matthew Keenan who, as a US marine, fought in Vietnam, the conflict has never ended. The war followed him back across the ocean, to live on in the form of cancer caused by exposure to the Agent Orange used by the US military. Driven by grief, guilt and a need to understand, Matthew has returned to Vietnam, searching for reconciliation.
