On the cusp of the second millennium, Frank Devlin is living a double life—schoolteacher by day and bomb expert by night.
No one, except Mac, Frank’s thorny boss in the Special Branch, not even his longstanding girlfriend, Una, knows that he is an undercover agent inside the IRA.
With the new peace agreement that aims to end the conflict in Northern Ireland, Frank thinks he will be able to come in from the cold, marry Una, and at last be able to stop looking over his shoulder. However, it is all wishful thinking, as Mac coerces him into infiltrating 1st May, a terrorist group in Athens, that desperately wants to avail of Frank’s knowledge and skills.
As he endeavors to pass muster with 1st May and get close to some of its members, Frank starts to question his beliefs and ideals. When the police begin to tighten the net around 1st May, Frank has finally decided where his loyalties lie —with 1st May or his fuliginous boss, Mac, with Una, his fiancée, or the sensuous Consuela, a fugitive Spanish terrorist, who has become his lover.
