Hidden Agenda (1990)

When an American human rights lawyer is assassinated in Belfast, it remains for the man's girlfriend, as well as a tough, no nonsense, police detective to find the truth... which they soon discover to be contained in an audio tape which the man had with him, exposing political manipulations at the highest levels of government. But such underlying agendas require careful considerations to avoid worse things than murder.
