A mixture of fact and speculation surrounding the death of U.S. President John F. Kennedy on 22nd November, 1963. New Orleans District Attorney, Jim Garrison, re-opens the files on the investigation and takes a critical look at the facts given by the F.B.I. His persistent questioning and poking his nose where it shouldn’t be causes his and his family’s lives to be at risk. But he keeps on the trail and soon uncovers a lead which points to the war in Vietnam.
