A patchwork portrait of an IRA Volunteer, Michael Wolfe Brock, who's ultimately ""beset by doubt"" when his services are utilized by the Abwehr for the destruction of England. A scene from his shattered childhood shows a youngster who gladly hides hand grenades under his mattress for his father. A socialist ""ambitious not for himself but for his beliefs,"" Brock later feels compelled to fight the Fascists in Spain in 1938. His loyalties begin to waver two years later in Coventry as German bombers prepare to zero in on his radio beam and strike a city of ""innocent"" Englishmen. He gives his life having realized the importance of trying to save others. This is somehow not as involving as it should be considering its jut-jawed determination and its sincerity.
