Befitting its title, Dublin Nightmare deals with the activities of the Irish Republican Army. British photographer John Kevin (William Sylvester) arrives in Dublin to attend the funeral of his friend. It turns, out however, that the friend isn't dead at all. Moreover, the "decedent" is an IRA leader, preparing for a bloody all-out offensive. John Tully's screenplay tries to cram way too much into a 64-minute running time.
